SYNTAX
FUNCTION
DESCRIPTION
writes the result into rdest. Rounding toward zero is performed; the IEEE rounding mode bits in PCSW are ignored.
This is the preferred rounding for ANSI C. If r src1 is denormalized, zero is substituted before conversion, and the IFZ
flag in the PCSW is set. If
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
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.
