29.7.6.11 Cylindrical Neumann functions [sf.cmath.cyl.neumann]

_floating-point-type_ cyl_neumann(_floating-point-type_ nu, _floating-point-type_ x);float cyl_neumannf(float nu, float x);long double cyl_neumannl(long double nu, long double x);

Effects: These functions compute the cylindrical Neumann functions, also known as the cylindrical Bessel functions of the second kind, of their respective argumentsnu and x.

Returns: , where is given by Formula 29.31,ν is nu, andx is x.

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