awkalc is a Dashboard widget to evaluate a formula (such as “sin(23)*cos(42)”) using awk.
Some functions (tan, asin, acos, atan, log10, abs) and constants (e, pi, dtor=pi/180) are implemented in addition to awk builtin ones (sin, cos, sqrt, log, exp, etc.).
Userdefined variables can be used like “x=23; y=42; sin(x)*cos(y)”.
What's New:
[new in 2.2.1] fixed a bug on trigonometric functions in "deg" mode [many thanks to Stefan!]
[new in 2.2] preserve result history.
[new in 2.1] improve behavior of trigonometric functions in "deg" mode.
[new in 2.0] support userdefined variables/preserve command history/implement abs() function/etc.
