SYNTAX
FUNCTION
DESCRIPTION
writes the result into r dest . Rounding is according to the IEEE rounding mode bits in PCSW. If r src1 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 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.
