[Octave-bug-tracker] [bug #47775] realpow and sparse-xpow.cc-tst fails

[Lachlan Andrew]

Follow-up Comment #10, bug #47775 (project octave):

OK. I'll try to make time this evening.

Note however that although the difference between real and complex is huge if
the input is real, it is not huge if the input is already complex, which is
the case here.

If the [3,4] in the test were replaced by [3+eps, 4+eps], then the true result
would indeed be complex.  If we want to treat integers as "special", then
there is a case for doing that ourselves, rather than relying on the complex
library to do it.  That is what I had to do in pown() in oct-stream.cc to get
1e+10 etc. to be exact integers in textscan.
