ICalc

ICalc v1.00 Copyright (C) 1996 by Ian Prest All rights reserved. What is ICalc? -------------- ICalc is a small, fast, FREE!, calculator-type program. How often have you wanted to make simple calculations, and not had a calculator handy? And how often have you resorted to starting QBasic or the Windows Calculator to make these simple calculations? ICalc has two modes - command-line mode and interactive mode. If you don't enter any command-line parameters, ICalc automatically enters interactive mode. ICalc is very simple, and was written in a couple of hours while I was trying to learn how to use YACC. Some of the code was stolen from HTML-Ed, and some was stolen from another project of mine, so I don't have too much time invested in it. So, I've decided to make it freeware. It's still very useful, however; I use it all the time. How to use ICalc: ----------------- From the command-line: ICalc <expression> where <expression> is any mathematical expression recognized by ICalc (whitespace is not allowed on the command line). From interactive mode: At the '>' prompt, enter any mathematical expression recognized by ICalc and press enter (whitespace is allowed in interactive mode). The result will be displayed. To access the command-line history, use the up and down arrows from the ICalc '>' prompt. To exit interactive mode, press enter at a blank '>' prompt. Recognized Expressions ---------------------- ICalc recognized the following operators: '+' and '-' for addition and subtraction '*' and '/' for multiplication and division '(' and '[' parentheses (the square brackets are merely for convenience) '%' for the remainder of a division '=' for variable assignment A variable name can be any combination of alpha-numeric characters (with the exception that it can't start with a number). Variables are _not_ case sensitive. The special variable "ans" holds the last answer that ICalc gave. Examples ICalc Output -------- ------------ 4+4 = 8 m=3 = 3 6+m = 9 hello=(4*5)+10 = 30 hello+3 = 33 7%3 = 1 ans+3 = 4 ans+3 = 7 Limitations ----------- ICalc currently does not handle floating-point math. It might at some point in the future, when/if I feel like adding it. I may also, at some point, extend its capabilities to include _infinite precision_ floating point math, when/if I feel like porting my infinite precision math library to C from either Basic or Pascal.

Contacting the Author --------------------- Feel free to contact me at ianprest@connect.reach.net. I cannot provide much support for this FREE program, but I will try to help with any problems you are having. Visit my home page at: http://www.wp.com/ianprest I will _not_ spend a lot of time fixing bugs and/or adding new features since this is a freeware utility. Most of my free time is already taken up with HTML-Ed (my HTML editor - http://www.wp.com/ianprest/htmled.html) and with school-work. Feel free to make requests, but don't expect anything.
