NetBSD 6.1.5 - man page for fesetround (netbsd section 3)

FEGETROUND(3)			   BSD Library Functions Manual 		    FEGETROUND(3)

NAME
     fegetround, fesetround -- floating-point rounding control

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 suc-
     ceeds.

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 and NetBSD 6.0.  They supersede the non-stan-
     dard fpgetround(3) and fpsetround(3) functions.
