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

SYNOPSIS
       #include 

       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; or
       cc -std=c99

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.

CONFORMING TO
       C99.
