Include: <math.h>
Syntax: long double _j0l( long double x );
long double _j1l( 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)
