RINT(3) 			   BSD Library Functions Manual 			  RINT(3)

NAME
     rint, lrint, llrint -- round to integral value

SYNOPSIS
     #include <math.h>

     double
     rint(double x);

     float
     rintf(float x);

     long int
     lrint(double x);

     long int
     lrintf(float x);

     long long int
     llrint(double x);

     long long int
     llrintf(float x);

DESCRIPTION
     The rint() and rintf() functions return the integral value nearest to x (according to the
     prevailing rounding mode) in floating-point format.

     The lrint() , lrintf() , llrint() and llrintf() functions return the integral value nearest
     to x (according to the prevailing rounding mode) in the return formats specified.	If the
     rounded value is outside the range of the return type, the numeric result is unspecified and
     the "invalid" floating-point exception is raised. A range error may occur if the magnitude
     of x is too large.

SPECIAL VALUES
     rint(+-0) returns +-0 for all rounding modes.

     rint(+-infinity) returns +-infinity for all rounding modes.

     All these functions raise the "inexact" floating-point exception if the result differs in
     value from the argument (except when they raise some other floating-point exception, such as
     "invalid").

SEE ALSO
     abs(3), fabs(3), ceil(3), floor(3), ieee(3), math(3)

STANDARDS
     The rint() , rintf() , lrint() , lrintf() , llrint() , and llrintf() functions conform to
     ISO/IEC 9899:1999(E).
