Follow-up Comment #11, bug #60539 (project octave):

doubles are much less of a problem, although the new algorithm produces
slightly different results from either Matlab or the previous algorithm.

Also, the algorithm definitely still needs to be accurate for single values
since they are an accepted input.  The old algorithm produces 0.9786913 for
the example code which is the same as Matlab.  It feels like a regression when
the old code was able to handle this input.
