AFAICT approximate equality checks aren't really useful for that, no. (I also don't understand why people in that argument are so worried about exact precision for 90° and 30° when it's impossible for all the other angles.) Python is *very* stingy with adding new operators; IIRC only 3 have been added over the last ~30 years (**, //, @). I don't think ~= is going to make it. -n -- Nathaniel J.
