Calc Lite for OS/2

___________________________________________________________ Calc Lite for OS/2 Copyright (c) 1998 Magnus Olsson. All rights reserved. Scientific CLI Calculator for 32-bit OS/2 ___________________________________________________________ Description =========== The "Calc Lite" calculator is a freeware version of the command line calculator included in the shareware WarpCalc. The only major difference is that this version is unsupported. System requirements =================== Calc Lite is a 32-bit OS/2 application and should run on OS/2 version 2.x and above. Licensing ========= Calc Lite is freeware, but is copyrighted and not in the public domain. Permission is granted to any individual or institution to use, copy, or redistribute this software so long as all of the original files are included unmodified, that it is not sold for profit, and that this copyright notice is retained. Documentation ============= The calculator can be passed a mathematical expression as a command line argument like this: calc pi The above command evaluates the name pi and displays the result using default settings. It then immediately returns to the command prompt. It is also possible to enter more than one expression at once, separating the different expressions with semicolons. calc "x= atan 2; sin x/cos x; tan x - ans" The first expression assigns the angle for tangens 2 to x. In the following expression the value of x is used to calculate tangens for x. The last expression should give the result zero (ans holds the result from the previous expression). When starting the calculator without passing any expressions the program will display a command prompt. From that prompt you can evaluate mathematical expressions and configure the calculators behavior. The prompt shows the angular unit currently used. Online help can be displayed by entering the internal command 'help'. For a list of help topics enter: 'help ?'. As a default the calculator uses a flexible result notation. Except for fix point notation the default precision is 15 significant digits (fix point notation uses 15 decimals). The default angle measurement unit used in conjunction with the trigonometric functions is radian. The defaults can be overridden through command line options as shown below. [ /not sci|fix|eng ][ /prec <n> ][ /unit deg|rad|gra ] To have the calculator use ANSI colors to highlight input and results add the following switch. [ /color ] For U.S. based users there is also a switch to force the calculator to use ISO signs for decimal separator, multiplication and the division. [ /iso ] Defaults for the command line switches can be set through the following environment variables: calc_not, calc_prec, calc_unit, calc_iso and calc_color. The options are the same as above except for calc_iso and calc_color, which take either a yes or a no. All environment variables are case insensitive. The internal command line works as follows. A block cursor indicates over-write mode and a line cursor insert mode. Escape erases the current input. Input history can be navigated with the up/down- keys.
