[Octave-bug-tracker] [bug #48307] sinc loses precision for large arguments

[Lachlan Andrew]

Follow-up Comment #25, bug #48307 (project octave):

Colin, comment #22: You have said that sinc doesn't have to be calculated in a
particular way.  I agree.  My point is that it doesn't matter how sinc is
calculated, because the problem is with the input argument.  That is what Dan
confirmed with comment #21:

"So, yes, it seems that most of the loss of accuracy is a result of the fact
the input (i.e., Octave's storage class) is double and not long double."
