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.
