RINT(3)				    NEWLIB			       RINT(3)

NAME
       1.48 `rint', `rintf'-round to integer

SYNOPSIS
	    #include <math.h>
	    double rint(double X);
	    float rintf(float X);

DESCRIPTION
       The `rint' functions round their argument to an integer value in float‐
       ing-point format, using the current rounding direction.	They raise the
       "inexact"  floating-point exception if the result differs in value from
       the argument.  See the `nearbyint' functions for the same function with
       the "inexact" floating-point exception never being raised.  Newlib does
       not directly support floating-point exceptions.	The  `rint'  functions
       are  written  so	 that  the  "inexact"  exception is raised in hardware
       implementations that support it, even though Newlib  does  not  provide
       access.

RETURNS
       X rounded to an integral value, using the current rounding direction.

PORTABILITY
       ANSI C, POSIX
