BTW ... looking closer at that, it appears to show asind(-0.5) and
asind(0.5) returning NULL. Which makes no sense at all, because
there is no provision in dasind() for returning a null, regardless
of the input value.
So I'm pretty baffled. Maybe you could step through this and figure
out where it's going off the rails?
