wcalc is a command-line calculator designed to accept all valid mathematical expressions. It supports all standard mathematical operations, parenthesis, brackets, trigonometric functions, hyperbolic trig functions, logs, and boolean operators.
wcalc accepts input in a variety of manners. If no mathematical expression is given at the commandline, it will evaluate the contents of an environment variable named wcalc_input if one exists. If that variable is not set, wcalc will try to read input from standard input (i.e. piped input). If there is no input from that, wcalc enters “interactive” mode. Interactive mode has more features.
This is free and open source software.
