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

NAME

     round, roundf - round to nearest integral value

LIBRARY

     libm

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).

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").

HISTORY

     The round() and roundf() functions appeared in NetBSD 2.0.
