awkalc

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 built-in ones (sin, cos, sqrt, log, exp, etc.). User-defined variables can be used like "x=23; y=42; sin(x)*cos(y)".
