Wcalc 2.3

Wcalc is a very capable calculator. Wcalc has standard functions (sin, asin, and sinh for example), many pre-defined constants (pi, e, c, etc.), support for using variables, a command history, hex/octal/binary input and output, unit conversions, bit-shifting, embedded comments, and an expandable expression entry field. It evaluates expressions using the standard order of operations.
Wcalc is a very capable calculator. It supports abitrary precision, has standard functions (sin, asin, and sinh for example, in either radians or degrees), many pre-defined constants (pi, e, c, etc.), support for using variables, "active" variables, a command history, hex/octal/binary input and output, unit conversions, embedded comments, and an expandable expression entry field. It evaluates expressions using the standard order of operations.
Wcalc uses intuitive expressions. For example, Wcalc will evaluate: 5sin 4!-7*2(4%6)^2 to be -221.96631678
Wcalc also comes in a command-line version that works on most (if not all) forms of Unix (including Linux and BSD). To support arbitrary precision, Wcalc relies on the GMP and MPFR libraries.
In the MacOSX release, these are compiled-in, so you shouldnt have to install them yourself. NOTE: GMP comes with a broken version of MPFR (I really wish they wouldnt do that). You have to install a real version of MPFR for Wcalc to work.
Enhancements:
- This has plenty of bugfixes and a couple nifty new features. In the GUI realm, Wcalc now also serves as a System Service, and so adds a "Wcalc Compute" entry to the Services menu of other applications.
- In the CLI realm, Wcalcs error reporting is now more friendly, and will tell you exactly where in the line the error occurred.
- Also, Wcalc now uses tab-completion in the CLI, and can tab-complete just about anything (variables, conversion units, commands, functions, etc.).
