Code:
{ Save the current FPU state and then disable FPU exceptions }
  Saved8087CW := Default8087CW;
  Set8087CW($133f); { Disable all fpu exceptions }
I have seen this line in a few 3D Engines, both Delphi & C++, however I have no clue what it does exactly... It disables FPU exceptions and FPU seems to be some sort of instruction set for the i386, but since I'm quite an ASM n00b I have no clue what it does! ops:

Can anyone explain it (generally) to me ? Thanks in advance!
