J0(3)				   BSD Library Functions Manual 			    J0(3)

NAME
     j0, j0f, j1, j1f, jn, jnf, y0, y0f, y1, y1f, yn, ynf -- Bessel functions of first and second
     kind

LIBRARY
     Math Library (libm, -lm)

SYNOPSIS
     #include <math.h>

     double
     j0(double x);

     float
     j0f(float x);

     double
     j1(double x);

     float
     j1f(float x);

     double
     jn(int n, double x);

     float
     jnf(int n, float x);

     double
     y0(double x);

     float
     y0f(float x);

     double
     y1(double x);

     float
     y1f(float x);

     double
     yn(int n, double x);

     float
     ynf(int n, float x);

DESCRIPTION
     The functions j0(), j0f(), j1() and j1f() compute the Bessel function of the first kind of
     the order 0 and the order 1, respectively, for the real value x; the functions jn() and
     jnf() compute the Bessel function of the first kind of the integer order n for the real
     value x.

     The functions y0(), y0f(), y1() and y1f() compute the linearly independent Bessel function
     of the second kind of the order 0 and the order 1, respectively, for the positive integer
     value x (expressed as a double); the functions yn() and ynf() compute the Bessel function of
     the second kind for the integer order n for the positive integer value x (expressed as a
     double).

RETURN VALUES
     If these functions are successful, the computed value is returned, otherwise the global
     variable errno is set to EDOM and a reserve operand fault is generated.
