RootM 1.2.2

RootM is an RPN scientific calculator for the Palm OS that natively support computations containing imaginary numbers. This means that sqrt(-1) or asin(2) are valid computations, producing complex results. Complex numbers can be entered in real/imag format or mag/phase format in a straightforward way. Quickly switch between real/imag and phasor (mag/phase) displays. RootM has a 16 high stack and 20 memory registers -- all of which can store complex results.
RootM is a advanced scientific and financial calculator too. RootM has functions to compute loan and mortgage terms and well as simple statistics.
