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.
