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);
Link with -lm.
Feature Test Macro Requirements for glibc (see **feature_test_macros(7)**):
All functions shown above:
_XOPEN_SOURCE >= 600 || _ISOC99_SOURCE ||
_POSIX_C_SOURCE >= 200112L;
or cc -std=c99
DESCRIPTION
These functions round their argument to the nearest integer value,
using the current rounding direction (see **fesetround(3)**).
Note that unlike the **rint(3)** family of functions, the return type of
these functions differs from that of their arguments.
RETURN VALUE
These functions return the rounded integer value.
If x is a NaN or an infinity, or the rounded value is too large to be
stored in a long (long long in the case of the ll* functions), then a
domain error occurs, and the return value is unspecified.
ERRORS
See **math_error(7)** for information on how to determine whether an error
has occurred when calling these functions.
The following errors can occur:
Domain error: x is a NaN or infinite, or the rounded value is too large
An invalid floating-point exception (FE_INVALID) is raised.
These functions do not set errno.
VERSIONS
These functions first appeared in glibc in version 2.1.
