29.7.6 Mathematical special functions [sf.cmath]

29.7.6.20 Spherical Bessel functions of the first kind [sf.cmath.sph.bessel]

_floating-point-type_ sph_bessel(unsigned n, _floating-point-type_ x);float sph_besself(unsigned n, float x);long double sph_bessell(unsigned n, long double x);

Effects: These functions compute the spherical Bessel functions of the first kind of their respective argumentsn and x.

Returns: , where is given by Formula 29.40,n is n, andx is x.

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