NAME
     j0, j0f, j0l, j1, j1f, j1l, jn, jnf, jnl - Bessel  functions
     of the first kind

SYNOPSIS
     c99 [ flag... ] file... -lm [ library... ]
     #include 

     double j0(double x);


     float j0f(float x);


     long double j0l(long double x);


     double j1(double x);


     float j1f(float x);


     long double j1l(long double x);


     double jn(int n, double x);


     float jnf(int n, float x);


     long double jnl(int n, long double x);


DESCRIPTION
     These functions compute Bessel functions of x of  the  first
     kind of orders 0, 1 and n respectively.

RETURN VALUES
     Upon  successful  completion,  these  functions  return  the
     relevant Bessel value of x of the first kind.


     If x is NaN, a NaN is returned.

ERRORS
     No errors are defined.
