RealCalc科学计算器使用说明
====Basic Operation=======Basic Operation===The number keys[0]to[9]and decimal point[DP]are used to enter numbers.To enter a negative number,press[SGN]after entering the number.To enter an exponent,press[EXP]then enter the exponent using the numberand[SGN]keys.The[DEL]key deletes the last digit entered and can be used to correct a number or exponent.The[CLR]key clears the display ready for a new calculation.The[SHIFT]key is used to access the secondary function of each key(displayed above the key in orange.While shift is active,'SHIFT'will be shown on thedisplay.Press[SHIFT]again to cancel shift mode.As an alternative to using shift,the secondary function of each key can also be accessed by holding down the key.This feature can be disabled in Settings.====Display Modes=======Display Modes===There are four display modes for calculation e the[FSE]key to cycle through the modes. The display will show'FIX','SCI','ENG'or blank to indicate the current mode.===Decimal Places===To set the number of decimal places in FIX,SCI or ENGmodes,press[SHIFT][TAB].This will bring up a dialog to select the number of placesfrom0to9,together with the current value rounded to each. ===Normal mode===The result is displayed as a normal floating point value if possible.If its magnitude is less than0.0001 or greater than9999999999,then scientific notation is used(see SCI mode below.The number of decimal places cannot be adjusted in this mode.===FIX mode(Fixed decimal point===The result is displayed after rounding to the number of decimal places selectedby[SHIFT][TAB].If there is not enough room,the result may be displayed with fewer decimal places.===SCI mode(Scientific notation===The result is displayed in the format A x10^B^,with the mantissa(Arounded to the number of decimal places selected by[SHIFT][TAB].===ENG mode(Engineering notation===This is the same as SCI mode,except that the exponent is set to a multiple of3.===Note===The value used for calculations is the unrounded result stored internally,and not the rounded value shown on the display.====Result History=======Result History===Each time the[EQU]key is pressed,the calculation result is added to a history list.The[ANS]key presents a dialog showing the calculation result history,with the most recent results at the top.Select the required value to enter it into the calculator.===History Size===The maximum number of results which are stored can be set via the Settings screen(Menu->Settings. When set to'Off',the[ANS]key simply recalls the last result,without showing a dialog.===Unique History===By default,the values in the history list are unique.If a calculation result is the same as one already in the history list,this value is moved to the top.This behaviour can be changed via the Settings screen. ===History Reset===The history list can also be cleared via the Settings screen.====Memories=======Main Memory===The main memory has four dedicated function keys:~[MS]stores the current display value into the main memory.~[MR]recalls the value stored in the main memory.~[MP]adds the current display value to the main memory.~[MM]subtracts the current display value from the main memory.Whenever a non-zero value is stored in the main memory,the letter'M'is shown on the display.The main memory can also be accessed via the[STO]and[RCL]keys(see below.===Additional Memories===There are nine additional memories which can be accessed viathe[STO]and[RCL]keys.These keys show a dialog with the current values stored in the main memory'M'and the additional memories'1' to'9'.Select the appropriate value to store or recall the memory value.===Memory Reset===The values stored in all the memories can be reset to zero via the Settings screen.====Unit Conversion=======Unit Conversion===The current display value can be converted between different units usingthe[CONV]key.~First,select the unit type from the list(distance,area,speed,time,etc.~Second,select the unit to convert from.Drag the list up/down to scroll if necessary.~The dialog will show the value converted to all appropriate units,with the original value highlighted in orange.~Select the required value to enter it into the calculator.~Press the back button at any time to go back to the previous step.===Zero Values===For most conversions,an original value of0.0will be replaced by1.0as a convenience to avoid converting zero to zero.This does not apply to conversions which are not a simple ratio,e.g. temperature.===Note===The unit conversion dialog only displays values in decimal,the current radixmode(BIN,OCT or HEXis ignored.====Basic Functions=======Arithmetic Calculations===These are entered exactly as written:25[MUL]3[EQU]{75.}Operations can be joined together:12[ADD]3[SUB]4[EQU]{11.}Multiplication and division have precedence over addition and subtraction and will be performed first: 1[ADD]2[MUL]3[EQU]{7.}The parentheses keys can be used to override the normal precedence:[OBKT]1[ADD]2[CBKT][MUL]3[EQU]{9.}There is no limit to the number of parentheses which can be entered.===Repeat Calculations===Repeat calculations can be performed without re-entering the value and function key,for example:10[ADD]20[EQU]{30.}20is now a constant for addition:60[EQU]{80.}30[EQU]{50.}[EQU]{70.}[EQU]{90.}Similarly for subtraction,multiplication and division: 10[SUB]3[EQU]{7.}15[EQU]{12.}7[EQU]{4.}5[MUL]2[EQU]{10.}7[EQU]{14.}100[DIV]4[EQU]{25.0}80[EQU]{20.}===Percentage Calculations===~What is10%of200?200[MUL]10[PC][EQU]{20.}~What percentage of36is9?9[DIV]36[PC][EQU]{25.}~What is a10%increase of200?200[ADD]10[PC][EQU]{220.}~What is a20%decrease of500?500[SUB]20[PC][EQU]{400.}===Powers and Roots===~Find20^2^20[SQR]{400.}~Find6^3^6[SHIFT][CUBE]{216.}~Find the square root of2525[SQRT]{5.}~Find the cube root of6464[SHIFT][CBRT]{4.}~Find the4th root of8181[SHIFT][ROOT]4[EQU]{3.}===Reciprocals===~Find1/41/54[SHIFT][OVER][ADD]5[SHIFT][OVER][EQU]{0.45} ===Constants===~Find2pi2[MUL][SHIFT][PI][EQU]{6.283185307}~Find1/e[SHIFT][E][SHIFT][OVER]{0.367879441}====Advanced Functions=======Logarithms and Exponentiation===~Find ln(20.120[DP]1[LN]{3.000719815}~Find log(316316[LOG]{2.499687083}~Find e^3^3[SHIFT][EX]{20.08553692}~Find10^2.5^2[DP]5[SHIFT][TENX]{316.227766}===Trigonometric Functions===For trigonometric functions,angles can be specified in degress,radians or gradients.The[DRG]key cycles through the angle modes,and the display will show DEG,RAD or GRAD to indicate the current mode.The[DRGC]key also cycles through the angle modes,but also converts the current value in the display.~Find sin(30(in DEG mode30[SIN]{0.5}~Find tan(pi/4(in RAD mode[SHIFT][PI][DIV]4[EQU][TAN]{1.}~Find arcos(0.5(in DEG mode[DP]5[SHIFT][ACOS]{60.}~Convert180degrees to radians180[DRGC]{3.141592654}===Hyperbolic Functions===For hyperbolic functions press the[HYP]key before pressing[SIN],[COS]or[TAN].For inverse hyperbolic functions use[HYP]in combination with[SHIFT].The'HYP'indicator will appear in the display.~Find sinh(44[HYP][SIN]{27.2899172}~Find arcosh(99[SHIFT][HYP][COS]{2.88727095}===Factorials and Permutations===~Find10!10[SHIFT][FACT]{3628800}~Find permutations of3items from55[SHIFT][NPR]3[EQU]{60.}~Find combinations of3items from55[SHIFT][NCR]3[EQU]{10.}====Binary,Octal and Hex=======Binary,Octal and Hexadecimal Modes===These modes are set using the[BIN],[OCT]and[HEX]keys respectively.The[DEC]key returns to the normal decimal mode.The current value on the display is converted when switching modes.When in BIN,OCT or HEX modes,calculations are performed on integer values upto12digits. Non-integer results will be truncated.===Digit Keys===~In binary mode,only the digit keys[0]and[1]are used.~In octal mode,only the digit keys[0]to[7]are used.~In hexadecimal mode,the digit keys[0]to[9]and[KPA]to[KPF]are used.===Negative Values===Negative values are represented in2's,8's or16's complement notation.Example:[SHIFT][DEC][1][SGN]{-1.}[SHIFT][BIN]{b-1.}[SHIFT][OCT]{o-1.}[SHIFT][HEX]{x-1.}Pressing the[SGN]key changes from normal to complementary form:[SHIFT][BIN]111[SGN]{b-7.}[SGN]{b7.}===Logical Operations===In BIN,OCT or HEX modes,additional logical operation keys become available: [NOT]-bitwise inversion[AND]-bitwise logical AND[NAND]-bitwise logical NAND[OR]-bitwise logical OR[NOR]-bitwise logical NOR[XOR]-bitwise exclusive-OR[XNOR]-bitwise exclusive-NOR===History and Memory Dialogs===When in BIN,OCT or HEX modes,the values in the history and memory dialogs are presented in the current mode.Values which cannot be converted to the current mode are shown as'Out of range'and cannot be selected.====RPN Mode=======Reverse Polish Mode===This mode is enabled via the Settings screen.In this mode,values are entered first,followed by the function key.Values are pushed onto a stack using the[ENTER]key.Functions take their arguments off the bottom of the stack,and push their result back onto the stack.The depth of the stack is unlimited.Functions which require a single argument,such as[SQR]or[SIN],simply operate on X and replace it,in the same way as normal mode:5[SQR]{X:25.}Functions which require two arguments,such as[DIV]or[POW],take X and Y off the stack and putthe result back: 30[ENTER]5[DIV] {X:6.} 2[ENTER]8[POW] {X:256.} ~ If the stack is empty, i.e. there is no value in the Y register, 'Arg?' will be displayed when trying to do an operation which requires two arguments. ~Find (4/(14[ENTER]5[ADD]1[ENTER]2[ADD][DIV] {X:3.} Note that as all operations are immediate, there is no need for parentheses or an equals key. ===Stack Operations=== The following additional functions are available in RPN mode: ~ The [DROP] key drops the X value off the bottom of the stack, shifting the remainder of the stack down. ~ The [SWAP] key swaps the values in the X and Y registers. ~ The [LASTX] key restores the value which was in the X register before the last operation. ~ The [VSTK] key opens a dialog which shows the contents of the stack. ===Display=== The display shows the current value at the bottom of the stack, X, and the next value, Y. This can be changed in the settings to show just the X register, or X, Y and Z. The size of the calculator keys is reduced compared to normal mode when showing X/Y or X/Y/Z. ===Result History=== As there is no equals key, the result of every operation is added to the result history.。

四、有关年金的终值与现值的计算——复利金融计 算模式（CMPD）
（一）年金的概念 年金（普通年金）：就是一组金额固定、时间间隔相等
并持续一段时间的现金流量。有时，也把这组现金流中每 期等额的现金称为年金。 例子1：定期定额投资500元，持续投资36个月，这500元就是 年金。 例子2：假如进行房屋抵押贷款的客户，其房贷每期要还4500 元，共持续20年，那么，这4500元的本利摊还额也是年金 。
（二）基本原理 FV PV (1 r)n
在以上四个变量中，只要已知三个变量的值，就能够计算出另一个未 知变量的值。
计算器将编写好的程序“固化”在其硬件上面。使用时只要严格遵守计 算器设定的规则输入数据就能计算出正确的答案。
注意：按照设定的规则输入数据，对于获得正确答案至关重要。
三、单笔现金流的终值、现值的计算 FV PV (1 r)n

Since many of Calc’s functions require very specific and carefully calculated input arguments, the descriptions in this appendix should not be considered complete references for each function. Refer to the application Help or the OOo wiki for details and examples of all functions. On the wiki, start with/wiki/Documentation/How_Tos/Calc:_Functions_liste d_by_categoryOver 300 standard functions are available in Calc. More can be added through extensions to Calc (see Chapter 14). The following tables list Calc’s functions organized into eleven categories.Note Functions whose names end with _ADD are provided for compatibility with Microsoft Excel functions.They return the same results as the corresponding functions in Excel (without the suffix), which though they may be correct, are not based on international standards.T erminology: numbers and argumentsSome of the descriptions in this appendix define limitations on the number of values or arguments that can be passed to the function. Specifically, functions that refer to the following arguments may lead to confusion.•Number_1; number_2;... number_30•Number 1 to 30• a list of up to 30 numbersThere is a significant difference between a list of number s (or integers) and the number of arguments a function will accept. For, example the SUM function will only accept a maximum of 30 arguments. This limit does NOT mean that you can only sum 30 numbers, but that you can only pass 30 separate arguments to the function. Arguments are values separated by semi-colons, and can include ranges which often refer to multiple values. Therefore one argument can refer to several values, and a function that limits input to 30 arguments may in fact accept more then 30 separate numerical values.This appendix attempts to clarify this situation by using the term arguments, rather than any of the other phrases.Mathematical functionsTable 1: Mathematical functionsFinancial analysis functionsA note about datesDate values used as parameters for Calc’s financial functions must be entered in a specific manner. For example, a date (entered in the US form) must be surrounded by quotes and with periods separating each value. To represent August 6, 2004, or8/6/04, you would enter “08.06.2004”. If you do not enter the date values as required by the function, you will not get the correct results. Date formats are locale specific; check the Help for the acceptable formatting.A note about interest ratesYou can enter interest rates in either of two ways:•As a decimal. To enter an interest rate as a decimal, divide it by 100 before entering it into a function. For example, to compute a loan with a 3.25%interest rate, enter .0325 into the function.•As a percentage. To enter an interest rate as a percentage, type in the interest rate followed by the % key. For example, to compute a loan with a 3.25%interest rate, enter 3.25% into the function.If you enter it as 3.25, the function will treat it as a 325% interest rate.Accounting systems vary in the number of days in a month or a year used in calculations. The following table gives the integers used for the basis parameter used in some of the financial analysis functions.Table 2: Basis calculation typesTable 3: Financial analysis functionsStatistical analysis functionsCalc includes over 70 statistical functions which enable the evaluation of data from simple arithmetic calculations, such as averaging, to advanced distribution and probability computations.Several other statistics-based functions are available through the Add-ins which are noted at the end of this appendix.Table 4: Statistical analysis functionsDate and time functionsUse these functions for inserting, editing, and manipulating dates and times. handles and computes a date/time value as a number. When you assign the number format “Number” to a date or time value, it is displayed as a number. For example, 01/01/2000 12:00 PM, converts to 36526.5. This is just amatter of formatting; the actual value is always stored and manipulated as a number. To see the date or time displayed in a standard format, change the number format (date or time) accordingly .To set the default date format used by Calc. go to Tools > Options > Calc > Calculate.When entering dates, slashes or dashes used as date separators may be interpreted as arithmetic operators. To keep dates from being interpreted as parts of formulas, and thus returning erroneous results, always place them in quotation marks, for example, "12/08/52".Table 5: Data and time functionsLogical functionsUse the logical functions to test values and produce results based on the result of the test.These functions are conditional and provide the ability to write longer formulas based on input or output.Table 6: Logical functionsInformational functionsThese functions provide information (or feedback) regarding the results of a test for a specific condition, or a test for the type of data or content a cell contains.Table 7: Informational functionsDatabase functionsThis section deals with functions used with data organized as one row of data for one record.The Database category should not be confused with the Base database component in . A Calc database is simple a range of cells that comprises a block of related data where each row contains a separate record. There is no connection between a database in and the Database category in OOo Calc.The database functions use the following common arguments:•Database is a range of cells which define the database.•Database_field specifies the column where the function operates on after the search criteria of the first parameter is applied and the data rows are selected.It is not related to the search criteria itself. The number 0 specifies the whole data range. To reference a column by using the column header name, placequotation marks around the header name.•Search_criteria is a cell range containing the search criteria.. Empty cells in the search criteria range will be ignored.Note All of the search-criteria arguments for the database functions support regular expressions.For example, “all.*” can be entered to find the first location of “all” followed by any characters.To search for text that is also a regular expression, precede every character with a \ character.You can switch the automatic evaluation of regular expressions on and off in T ools > Options > Calc > Calculate.Table 8: Database averageArray functions Table 9: Array functionsSpreadsheet functionsUse spreadsheet functions to search and address cell ranges and provide feedback regarding the contents of a cell or range of cells.You can use functions such as HYPERLINK() and DDE() to connect to other documents or data sources.Table 10: Spreadsheet functionsT ext functionsUse Calc’s text functions to search and manipulate text strings or character codes.
