29.7.6 Mathematical special functions [sf.cmath]

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

_floating-point-type_ cyl_bessel_j(_floating-point-type_ nu, _floating-point-type_ 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: , where is given by Formula 29.29,ν is nu, andx is x.

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