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.
