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 argu- ment (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).
