```LRINT(3)						   BSD Library Functions Manual 						  LRINT(3)

NAME
llrint, llrintf, llrintl, lrint, lrintf, lrintl -- convert to integer

LIBRARY
Math Library (libm, -lm)

SYNOPSIS
#include <math.h>

long long
llrint(double x);

long long
llrintf(float x);

long long
llrintl(long double x);

long
lrint(double x);

long
lrintf(float x);

long
lrintl(long double x);

DESCRIPTION
The lrint() function returns the integer nearest to its argument x according to the current rounding mode.  If the rounded result is too
large to be represented as a long value, an invalid exception is raised and the return value is undefined.  Otherwise, if x is not an inte-
ger, lrint() raises an inexact exception.	When the rounded result is representable as a long, the expression lrint(x) is equivalent to
(long)rint(x) (although the former may be more efficient).

The llrint(), llrintf(), llrintl(), lrintf(), and lrintl() functions differ from lrint() only in their input and output types.

lround(3), math(3), rint(3), round(3)

STANDARDS
These functions conform to ISO/IEC 9899:1999 (``ISO C99'').

HISTORY
The llrint(), llrintf(), lrint(), and lrintf() routines first appeared in FreeBSD 5.4.  The long double variants were introduced in
FreeBSD 8.0.

NAME
lrint, lrintf, lrintl, llrint, llrintf, llrintl - round to nearest integer

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 x 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
x is too large.

RETURN VALUE
The rounded integer value.

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