Description Yields the integral value nearest to X. The function yields the integral value nearest to X. If X lies exactly halfway between two integers, one of those integers is returned, but which of them is returned is unspecified. A zero result has the sign of X when S'Signed_Zeros is True. This function provides access to the rounding behavior which is most efficient on the target processor. Example S’Machine_Rounding (X:T) return T
