RPN

A collection of powerful RPN calculator programs for the SHARP PC-G850(V)(S) and PC-1475.

PC-G850

The RPN programs are written in BASIC. The programs can be easily extended to add custom operations and user-defined functions.

Familiarity with RPN calculators, in particular the HP-15C, is recommended.

Features

  • complex arithmetic with separate stack registers for real and imaginary parts
  • 10 memory registers R0 to R9
  • one and two variable statistical functions
  • regression
  • hyperbolic and trigonometric functions for complex values
  • coordinate conversions to polar and rectangular
  • combinatorial functions nPr, nCr and !
  • gamma function
  • GCD and LCM
  • rational approximation of a decimal
