Looks like you are right. I'll leave it to others to add it to the
list, but here's the section from the standard:
7.12.9.5 The lrint and llrint functions
Synopsis
[#1]
#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
[#2] The lrint and llrint functions round their argument to
the nearest integer value, rounding according to the current
rounding direction. If the rounded value is outside the
range of the return type, the numeric result is unspecified.
A range error may occur if the magnitude of x is too large.
Returns
[#3] The lrint and llrint functions return the rounded
integer value.
