NAME
     round, roundf — round to nearest integral value

LIBRARY

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).

STANDARDS
     The round() and roundf() functions conform to ISO/IEC 9899:1999
     (“ISO C99”).

HISTORY
