Straight from Borland docs:
Default8087CW is the value to which the Floating Point Unit (FPU) control register is set. The FPU control word includes bits that control the FPU's precision, rounding mode, and whether exceptions generate signals if they occur.
So this:[pascal]Set8087CW($133f); { Disable all fpu exceptions }[/pascal]Disables all FP-coprocessor exceptions. By default in Delphi/C++Builder: InvalidOp, ZeroDivide, Overflow exceptions are enabled and RAISED in BAD CODE!!!
