[Octave-bug-tracker] [bug #43349] asin() behaves differently from Matlab for arguments larger than 1

[John W. Eaton]

Follow-up Comment #19, bug #43349 (project octave):

I don't understand why we should forward (x,0) to the complex asin function if
x < 0 but (x,-0) if x >= 0.  We're trying to define a function of a
real-valued argument, so why should we assign a negative imaginary part for
that value?

I'm also not sure that checking for a zero imaginary part as I did in my
second patch is really the best solution either.  It's just slightly less
duplicated code.

I'll look at this a bit more, but I think we should strive for the solution
that will be easiest to understand later.
