OK, the Phloat::pow() fix will be in 1.5.2. Still a lot of work to do on the new state file format, so probably no sooner than next weekend.

if x = 45 then x := SQRT(0.5);
else do

It didn't seem relevant to the angle reduction, but I had ignored the sin(45°) = cos(45°) issue. I'll add that in 1.5.2 as well.
By the way, where can I find out what formatting is supported on this forum? I thought it was strictly plain text here until I saw your [b] tags. :-)
(UPDATE: Duh, Help -> Posting -> MyCode. Never mind!)

The grads code is identical, just s/45/50/g etc.
Polar mode doesn't affect anything; complex numbers are always rectangular internally, and converted to polar only for display. The polar-to-rectangular conversion does rely on your angle reduction; see generic_p2r() in core_helpers.cc.

Thanks very much for you help!
