rpnExpress is a keyboard-centric calculator which uses the GMP and MPFR libraries to handle the mathematical operations. It supports both RPN and algebraic input mode.
It grew out of our own needs for a fast versatile RPN calculator with small memory footprint that can be controlled from the keyboard and supports very large integers.
The main features of this calculator are:
- All commands are entered from the keyboard, minimising the need to move your hand to the mouse or trackpad.
- It can handle very large integers and floating numbers with extreme precision.
- Values and command sequences can be saved into named variables and recalled later for calculations.
- You can enter and display numbers in any base between 2 and 36 inclusive.
- You can group the digits for easier reading of e.g. hex and binary values.
- It has both a RPN mode and algebraic mode.
- A declaration generator for exporting large integers to C arrays.
- It has over 60 powerful functions:
-- Number theoretical functions like the Riemann Zeta function
-- Primality testing
-- Trigonometric functions
-- Logical bitwise operations
-- Calculator control functions.
