FP_FAST_FMAD64
, FP_FAST_FMAD128
, FP_FAST_FMAD32
Definition of FP_FAST_FMAD64
indicates that the fmad64() function generally
executes about as fast as, or faster than, a multiply and add of
_Decimal64
operands. FP_FAST_FMAD128
and _FAST_FMAD32 are
_Decimal128and_Decimal32 analogs of FP_FAST_FMAD64
.
To use any of the types or macros for decimal floating point, define
__STDC_WANT_DEC_FP__
,either
with a
-D__STDC_WANT_DEC_FP__
compile option, or with
#define __STDC_WANT_DEC_FP__
in the source file before inclusion of
<math.h>.
