ROUND(3) NEWLIB ROUND(3)NAME
1.49 `round', `roundf'-round to integer, to nearest
SYNOPSIS
#include <math.h>
double round(double X);
float roundf(float X);
DESCRIPTION
The `round' functions round their argument to the nearest integer value
in floating-point format, rounding halfway cases away from zero,
regardless of the current rounding direction. (While the "inexact"
floating-point exception behavior is unspecified by the C standard, the
`round' functions are written so that "inexact" is not raised if the
result does not equal the argument, which behavior is as recommended by
IEEE 754 for its related functions.)
RETURNS
X rounded to an integral value.
PORTABILITY
ANSI C, POSIX
