CalcTastic is a feature-rich calculator with years of refinement and exceptional person scores. Choose from 12 different themes, a configurable display and your alternative of operation, Algebraic or RPN.

CalcTastic includes two fully-independent modes: A High-Precision Scientific Calculator with Fractions, Complex Numbers, Physical Constants, a Unit Converter, Advanced Statistics, History Memory Registers and a full-online Help Section.

CalcTastic is also a full-featured Programmer's Calculator with a dedicated Binary Display, help for Signed Unsigned Integers (from 8-64 bits) in addition to separate History Memory Registers (viewable in binary, octal, decimal or hex).
