lrint(3)
NAME
llrint, llrintf, lrint, lrintf -- convert to integer
LIBRARY
Math Library (libm, -lm)
SYNOPSIS
#include <math.h> long long llrint(double x); long long llrintf(float x); long lrint(double x); long lrintf(float 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 integer, lrint() raises an inexact exception. When the rounded result is repre- sentable as a long, the expression lrint(x) is equivalent to (long)rint(x) (although the former may be more efficient). The llrint(), llrintf(), and lrintf() functions differ from lrint() only in their input and output types.

The llrint(), llrintf(), lrint(), and lrintf() functions conform to ISO/IEC 9899:1999 (``ISO C99'').
