[Octave-bug-tracker] [bug #64801] besselj(1, z) is not pure imaginary for pure imaginary inputs

[Arun Giridhar]

Follow-up Comment #8, bug #64801 (project octave):

I'm still very ambivalent about whether it is a good idea to rewrite a
numerical answer with known floating point characteristics to its mathematical
counterpart. From a mathematical purity pov, that's OK, but it would hide any
signs of e.g. badly conditioned inputs. Tough to assess that tradeoff.
