Subject: | Complex NaN / infinity? |
Hi, It's been reported before as a bug [1] that Caml's Complex module doesn't properly support complex NaN and infinities: the current behavior is that expressions such as "div one zero" return a complex number with real and imaginary parts both set to NaN. The proper behavior would be to return a value representing directed or complex infinity, depending on whether "zero" is directed or not. Avoiding infinite results doesn't help either, since expressions such as "pow zero one" rely on infinity internally. Has anyone made a replacement module fixing these problems? I've started work on a replacement which uses both polar and Cartesian representations internally but I figure I'd ask before duplicating work. - Chris King [1] http://caml.inria.fr/mantis/view.php?id=1817
