26.8.6.8 Cylindrical Bessel functions of the first kind [sf.cmath.cyl.bessel.j]

double cyl_bessel_j(double nu, double x);float cyl_bessel_jf(float nu, float x);long double cyl_bessel_jl(long double nu, long double x);

Effects:These functions compute the cylindrical Bessel functions of the first kind of their respective argumentsnu and x.

Returns:
whereν is nu andx is x.

Remarks:The effect of calling each of these functions is implementation-defined if nu >= 128.
