FUNCTION
DESCRIPTION
format and writes the result into rdest. Rounding is performed toward zero; the IEEE rounding mode bits in PCSW are
ignored. This is the preferred rounding mode for ANSI C. If
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
the PCSW exception flags occurs at the same time as rdest is written. If any 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 r guard 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.
