Oh dear - I completely forgot the previous thread that I started on this : http://mail.scipy.org/pipermail/numpy-discussion/2011-November/059233.html You young people, don't laugh, this will happen to you one day. Anyway, summarizing, it appears that windows float96: a) Is stored as an 80 bit extended precision number b) Uses float64 precision for all calculations. c) Is specific to MingW builds of numpy - I think. Perhaps David C you'll correct me if I've got that wrong, Best, Matthew _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
