j0(3M)							  Mathematical Library Functions						    j0(3M)

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

SYNOPSIS
       cc [ flag... ] file... -lm [ library... ]
       #include <math.h>

       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.
