Of course, how stupid of me. I guess it should really be something
like signum(remainder(x, 2*%pi)), but I can't find a remainder
function that would be appropriate, or even a function to produce the
integer part.
But at least the corresponding fix for sinh would work since sinh
isn't periodic. :-)
Oh well.
