Division problem

[raymond]

If you ever need to divide a large number exceeding 32 bits by a divisor that would be smaller than the upper 32 bits of that large number, it is still possible to perform a division to obtain the quotient (which would be larger than 32 bits) and the remainder, but you would need a special approach which cannot be done with a single instruction (unless you switch to 64-bit assembly :bg).

yes - you can learn about the FPU in Ray's tutorial
and - he also has a nice floating point library   :U

the FPU allows you to handle very large and very small values

Cek for 0, division by zero sometime causing GPF on my old machine.

Amazing responses! Exactly what you are looking for as a beginner. Big thanks!

About the FPU-library, do you guys know if Iczelion guides through it in his tutorials? I'm at level tutorial 15 at the moment. Trying to use pure assembly more then macros like he does. Besides that I find the tutorial to be very useful. He have a part about multithread programming and I always wondered how to do that. Same goes for FPU-programming.

no - Iczelion does not go into the FPU - that is how to get started with windows
Ray's tutorial is great - the FPU is not as hard as one might think

I love Ray's page already :)
