NAME
round, roundf -- round to nearest integral value
LIBRARY
Math Library (libm, -lm)
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 func-
tions return the integral value with the larger absolute value (i.e., they round away from zero).
