ROUND(3)

NAME
round, roundf, roundl - round to nearest integral value

SYNOPSIS
libm
#include <math.h>
double
round(double x);
float
roundf(float x);
long double
roundl(long double x);

DESCRIPTION
The round(), roundf() and roundl() 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).

STANDARDS
These functions conform to isoC-99.
