CALC-WWW

calc-WWW is a simple but powerful scientific calculator accessible from any web browser.

calc-WWW has a keyboard driven, equation oriented user interface. It's features include:
 * all sets of parenthesis useable
 * multiple equations analyzed per request
 * implicit multiplication (or implicit addition)
 * 35 built in functions, including the trigonometric functions.
 * User defined functions and variables.
 * Analytic derivatives and simplification of user defined functions.

Notes:
 * calc-WWW requires the SRE-http web server - at this time, there is no CGI version of calc-WWW.
 * calc-WWW is a WWW version of a more complete DOS program.

CALCWWW is based on an aging, but still powerful, standalone DOS calculator.
