Engineering format

Hi, I wrote this program for my own use when working on electronic designs (e.g. to get the right values of capacitor in pF or uF). It imitates the function ←ENG and ENG→ as in HP35S and most other ALG scientific calculators. This is just a simple program, and for most people who don't need this fun...

E.g. if we want to XOR these hex numbers...
