NAME
j0, j0f, j0l, j1, j1f, j1l, jn, jnf, jnl - Bessel functions of the first kind
SYNOPSIS
c99 [ 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.
