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

[Rik]

Follow-up Comment #18, bug #43349 (project octave):

If I swap out the signbit call and just use x < 0 in the test then the
performance advantage is down to 0.5%.


  return fabs (x) > 1.0 ? asin (Complex (x, x < 0 ? 0.0 : -0.0))
                        : Complex (asin (x));


I'd say it is now just a question of which is more appealing code.  I think
modifying the phase angle is less invasive, but it might run into differences
between compilers and platform differences on Windows.
