Formulas based on physical RAM probably work well on Linux, but not so well on Windows: Windows has no "overcommit". Whether a virtual memory request succeeds on Windows depends on how much RAM (+ swap space, if any) has already been requested across all processes. It doesn't matter whether pages have actually been created, merely the total number of pages that _may_ be created. I never bumped into this issue before, because I never used MAX_PREC before ;-) When I intended to do exact arithmetic in `decimal`, I did this instead: - guesstimated the max number of decimal digits a computation would need - set `prec` to be comfortably - but not massively - larger than that - enabled the Inexact trap, so if I guessed too low I'd get an exception Maybe the docs could suggest that instead? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39576> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
