Working With the FPU

[grubish]

Just found some tutorials on ollydbg and since it has been mentioned a couple of times today, I'll make an effort to learn 'how to use it'. I mean I sometimes write code in emu8086 and it gives a very clear view of the inner workings and what I'm wrong about.

Trying to use the FPU without any of the basic knowledge of how it works will only bring you headaches. Spending a little time and effort on learning the basics would be a great investment. Have at least a glance at the first 2 chapters of the following FPU tutorial:
