_ _CPYSNF Intrinsic

The _ _CPYSNF intrinsic has the following declaration:

float __CPYSNF(float, float);

This intrinsic function performs a similar action as the _ _CPYSF intrinsic (described above), but where the sign of the first argument is negated before being combined with the magnitude of the second argument. This has the effect that the result has the opposite sign as the first argument, but has the magnitude of the second argument.
