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).

SEE ALSO
     ceil(3), floor(3), math(3), rint(3), trunc(3)

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