SYNOPSIS

#include <math.h>

long int lrint(double x);

long int lrintf(float x);
long int lrintl(long double x); long long int llrint(double x);
long long int llrintf(float x);
long long int llrintl(long double x);
 

DESCRIPTION

These functions round their argument to the nearest integer value, using the current rounding direction. If fIxfP is infinite or NaN, or if the rounded value is outside the range of the return type, the numeric result is unspecified. A domain error may occur if the magnitude of fIxfP is too large.  

RETURN VALUE

The rounded integer value.  

ERRORS

EDOM
The magnitude of fIxfP is too large and (math_errhandling & MATH_ERRNO) is non-zero.
