Wcalc is a powerful arbitrary-precision calculator. It has standard functions (sin, asinh, logtwo, floor, etc), many pre-defined constants (pi, e, c, etc.), variables, "active" variables, command history, and hex/octal/binary i/o, conversions, and more.

A command-line utility is also included, with all the same functions, making Wcalc a powerful replacement for the venerable bc and dc utilities.
