FE_DEC_TOWARDZERO
The round-toward-zero decimal rounding direction mode.
FE_DEC_TONEARESTFROMZERO
The round-to-nearest decimal rounding direction mode with ties (half-way
cases) away from zero.
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
<fenv.h>.
