Summary

Masks additional exceptions.

Pascal

 function Mask8087Exceptions(Exceptions: T8087Exceptions): T8087Exceptions;

Return Value

The set of exceptions that were masked upon routine entry. Upon exit the set of masked exceptions equals Result plus Exceptions.

Exceptions

Exceptions to be masked.

Description

Mask8087Exceptions masks the exceptions specified by the Exceptions parameter. Unlike SetMasked8087Exceptions the original exception mask is left intact. For example, if the current exception mask equals [emInvalidOp, emDenormalizedOperand], and you call Mask8087Exceptions([emZeroDivide]), then upon return the exception mask equals [emInvalidOp, emDenormalizedOperand, emZeroDivide].
