unsigned int _clearfp(void)

Gets and clears the floating-point status word.

unsigned int _controlfp (unsigned int, unsigned int)

Gets and sets the floating-point status word.

int _fpieee_flt(__in unsigned long _ExceptionCode, __in struct _EXCEPTION_POINTERS* _PtExceptionPtr, __in int (*_Handler)(_FPIEEE_RECORD*))

Invokes an user-defined trap handlet for IEEE floating-point exceptions.

void _fpreset(void)

Resets the floating-point package.

double _frnd(__in double _X)
