RINT(3)               DragonFly Library Functions Manual               RINT(3)

NAME
     nearbyint, nearbyintf, nearbyintl, rint, rintf, rintl -- round to
     integral value in floating-point format

SYNOPSIS
     #include <math.h>

     double
     nearbyint(double x);

     float
     nearbyintf(float x);

     long double
     nearbyintl(long double x);

     double
     rint(double x);

     float
     rintf(float x);

     long double
     rintl(long double x);

DESCRIPTION
     The rint(), rintf(), and rintl() functions return the integral value
     nearest to x according to the prevailing rounding mode.

     The nearbyint(), nearbyintf(), and nearbyintl() functions do the same,
     but without raising the ``inexact'' floating-point exception.

SEE ALSO
     abs(3), ceil(3), fabs(3), floor(3)

HISTORY
     A rint() function appeared in Version 6 AT&T UNIX.
