NAME
       lround,  lroundf, lroundl, llround, llroundf, llroundl - round to near-
       est integer, away from zero

SYNOPSIS
       #include <math.h>

       long int lround(double x);
       long int lroundf(float x);
       long int lroundl(long double x);

       long long int llround(double x);
       long long int llroundf(float x);
       long long int llroundl(long double x);

DESCRIPTION
       These functions round their argument  to  the  nearest  integer  value,
       rounding  away from zero, regardless of 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.
