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 *See Also*
`nearbyint', `rint'
