fegetround
() function determines the current
floating-point rounding mode, and the fesetround
()
function sets the current rounding mode to round. The
rounding mode is one of FE_TONEAREST
,
FE_DOWNWARD
, FE_UPWARD
, or
FE_TOWARDZERO
, as described in
fenv(3).
fegetround
() routine returns the current rounding
mode. The fesetround
() function returns 0 on success
and non-zero otherwise; however, the present implementation always succeeds.
fegetround
() and
fesetround
() functions conform to
ISO/IEC 9899:1999 (“ISO C99”).
