fegetround
FEGETROUND(3) BSD Library Functions Manual FEGETROUND(3)
NAME
fegetround, fesetround -- functions providing access to the floating-point rounding mode.
SYNOPSIS
#include <fenv.h>
#pragma STDC FENV_ACCESS ON
int
fegetround(void);
int
fesetround(int round);
DESCRIPTION
These functions provide control of floating-point rounding direction modes.
The fegetround() function gets the current rounding direction. It returns the value of the rounding direction macro representing the current
rounding direction, or a negative value if either there is no corresponding macro or if the rounding direction is not determinable.
The fesetround() function sets the rounding direction to be that specified by the argument round. If the argument is not equal to the value
of one of the rounding direction macros, the rounding direction is not changed. It returns zero if and only if the requested rounding direc-
tion was established.

STANDARDS
These functions conform to ISO/IEC 9899:TC3.
