  Include:   <math.h>
 
  Syntax:    long double _j0l( long double x );
             long double _j1l( long double x );
             long double _jnl( int n, long double x );
             long double _y0l( long double x );
             long double _y1l( long double x );
             long double _ynl( int n, long double x );
 
  Returns:   the result of a Bessel function of <x> if successful.
             (_y0l, _y1l, and _ynl return -HUGE_VAL if <x> is negative.)
             errno: EDOM (set by _y0l, _y1l, and _ynl if <x> is negative)
