It works fine on all other 11 platforms of Debian. Floating point math a bit different on the ARM? The quoted result is basically sqrt(200::float8), and we've never before heard reports of different platforms printing different answers, though I suppose it's possible if the FP hardware is not IEEE-spec. I'd suggest asking whoever maintains libm for Debian. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
