NAME
     j0, j1, jn, y0, y1, yn - bessel functions

SYNOPSIS
     #include <math.h>

     double j0(x)
     double x;

     double j1(x)
     double x;

     double jn(n,x)
     int n;
     double x;

     double y0(x)
     double x;

     double y1(x)
     double x;

     double yn(n,x)
     int n;
     double x;

DESCRIPTION
     These functions calculate Bessel functions of the first and
     second kinds for real arguments and integer orders.

DIAGNOSTICS
     On a VAX, negative arguments cause y0, y1 and yn to return
     the reserved operand and set errno to EDOM.
