y0(), y1(), yn(), Bessel functions of the second kind

These functions compute Bessel functions of the second kind. y0 and y1 compute the functions of order 0 and 1 respectively. yn computes the function of order n.

double y0(double x); double y1(double x); double yn(int, double);

If x is positive and exceeds π times 252, these functions return an ERANGE error, denoting total loss of significance in the result.


If you are migrating from RVCT, be aware that these functions are deprecated in ARM Compiler 4.1 and later.
