Nope. Well-known constant.

It _is_ a sketchy line. In that case you can be damn sure that constants
had been derived from other form. And you need that other form to do any
modifications that wouldn't turn the thing into random junk.

Normally you don't need it, unless you feel that one you have in glibc is
not good enough for your needs or want to experiment with modifying it.
Or analise the thing.

It's pretty similar to the case in question. The only difference is that
information needed to implement Bessel functions from scratch is easier
to find. However, it will be reimplementing from scratch. It won't help
you to answer any questions about the accuracy of implementation in glibc,
