ROUND(3)		  OpenBSD Programmer's Manual		      ROUND(3)

NAME
     round, roundf - round to nearest integral value

SYNOPSIS
     #include <math.h>

     double
     round(double x);

     float
     roundf(float x);

DESCRIPTION
     The round() and roundf() functions return the nearest integral value to
     x; if x lies halfway between two integral values, then these functions
     return the integral value with the larger absolute value (i.e., they
     round away from zero).

     ceil(3), floor(3), lrint(3), lround(3), math(3), nextafter(3), rint(3),
     trunc(3)
