SYNTAX
FUNCTION
DESCRIPTION
integer in rsrc1 to a single-precision IEEE floating-point value, and an integer bit vector representing the computed
exception flags is written into rdest. The bit vector stored in rdest has the same format as the IEEE exception bits in
the PCSW. The exception flags in PCSW are left unchanged by this operation. Rounding is performed toward zero;
the IEEE rounding mode bits in PCSW are ignored.
controls the modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not
changed.
