As regards Inf, this makes sense, because with +Inf and -Inf order is preserved. With one unsigned Inf nothing is really < or > than anything else.
To support this behaviour uniformly one would need a +0 or -0 offset for each number, which would lead straightforward to non-standard analysis ...
It's worse: Since according to IEEE +0 is not equal to -0, atan2 is not a function! Ben
