SYNTAX
FUNCTION
DESCRIPTION
writes the result into rdest. Rounding is according to the IEEE rounding mode bits in PCSW. If rsrc1 is denormalized,
zero is substituted before conversion, and the IFZ flag in the PCSW is set. If
such as overflow or underflow, the corresponding exception flags in the PCSW are set. The PCSW exception flags
are sticky: the flags can be set as a side-effect of any floating-point operation but can only be reset by an explicit
writepcsw
other floating-point compute operations update the PCSW at 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 rguard is 1, rdest and the exception flags in PCSW are written;
otherwise, rdest is not changed and the operation does not affect the exception flags in PCSW.
