There are two reasons for the bug.
(1) The coefficients in the series are not precise enough to get more than float
accuracy.
(2) The switch to the approximation at x>8 is much to early.
I applied the same solution as for BesselJ (see issue 40309) to BesselY too.
Because someone who will work on it later needs an detailed explanation how the
implementation correspond to the algorithm in the book, I have not included it
in the code, but will attach a description here.
The patch is based on the already integrated patch of issue 40309.
