fesetround(int
round);
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”).
