IronCalc

A simple engineering calculator with support for complex numbers and various number systems.

Documentation

The expression value calculation is implemented using IronPython, which explains the following features:

• The expression is not limited to one mathematical operation 2+3*4*(5+6*7)-sqrt(2)
• If at least one operand is a real number, the result of the expression will be real 2/3=0 and 2./3=0.666666666667
• Special variable _ - stores the result of the last calculation
• The implementation of mathematical functions is in the calc.py file and can be supplemented or changed as needed.
