Simple example of FPU.

[Farabi]

Here is the example how to use FPU spesific for OpenGL.

Code Select Expand


;Generate a Float number from integer

IntegerToFloat proc Number:dword

push Number
fild dword ptr[esp]
fstp dword ptr[esp]
pop eax

ret
IntegerToFloat endp ; Return Value is eax=real4 format of Number


Dont use this function on the realtime calculation. fild function can cause the light disable.

Check also fsub, fadd and fmul. Dont use fisub, fadd, fimul.
