the result is an integer. If an argument is denormalized, zero is substituted for the argument before computing the

same time, the net result in each exception flag is the logical OR of all simultaneous updates ORed with the existing
PCSW value for that exception flag.
modification of the destination register. If the LSB of r guard is 1, r dest and the exception flags in PCSW are written;
otherwise, r dest is not changed and the operation does not affect the exception flags in PCSW.
