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 2

`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.
