Mac Vs. Linux

It took me more than two weeks! Yes exactly more than two weeks!!
What was it? Simple, I had a code which ran fine on Mac but not Linux! It was not compile error it was just different results...

The answer to this riddle was solved tonight after lots of checking, reimplementing, ...

"Linux (on 32 bit AMD) and Mac (on G4 power book) machines do binary operations differently!"

So if you don't want to be lost in your program for more than two weeks after you port your program keep this in mind ...
