This function returns a nonzero value if floating-point operations are emulated otherwise, it returns zero. PF_FLOATING_POINT_PRECISION_ERRATA 0, Windows operating systems that don’t support the fast fail instruction natively will typically treat a fast fail request as an access violation, or as an UNEXPECTED_KERNEL_MODE_TRAP bugcheck. In these cases, the program is still terminated, but not necessarily as quickly. __fastfail is only available as.
