NAME

fegetround, fesetround – floating-point rounding control

CONTENTS

LIBRARY

Math Library (libm, -lm)

SYNOPSIS

#include <fenv.h>

#pragma STDC FENV_ACCESS ON
int
fegetround(void);

int
fesetround(int round);

DESCRIPTION

The 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).

RETURN VALUES

The fegetround() routine returns the current rounding mode. The fesetround() function returns 0 on success and non-zero otherwise; however, the present implementation always succeeds.

SEE ALSO

fenv(3), fpgetround(3), fpsetround(3)

STANDARDS

The fegetround() and fesetround() functions conform to ISO/IEC 9899:1999 ("ISO C99").

HISTORY

These routines first appeared in FreeBSD 5.3 . They supersede the non-standard fpgetround(3) and fpsetround(3) functions.
