WindowCE altready contains a calculator. Nevertheless, this calculator is quite a simple one and can make standard calculations like *, -, /, + and square root extraction.

RealCalculator can do much more. It includes:

• Scientific calculator
• Function plotter
• Matrix-calculator
• Calculator for complex numbers
• Computer-calculator (hex, bin, oct, dec)
• Function calculator
• Numerical equations solver
• Statistic calculator
• Metrics-converter

Apart from that, it pursuits a different concept: Normally, all input is directly calculated, so you have problems with the sequence of your operations (e.g. * comes before -). RealCalculator stores all input in the input-field(s) and makes the calculation not until you have pressed the "="-button.
