Thanks for the explanation, Robert Kern. It seems then that indeed, these days the optimal default would be `fmt='%.16e'`.
The test on StackOverflow was just a quick demonstration. See also the description for `DBL_DECIMAL_DIG` here: https://en.cppreference.com/w/cpp/header/cfloat > But if your true concern is that 9% of disk space, > you probably don't want to be using `savetxt()` in any case. Well, I do in fact want to save as text, but I would rather not do so in an unnecessarily wasteful fashion. So i just set `fmt='%.16e'` myself, no biggie. The point, however, is that most users will not set this, and so `savetxt()` is a cause of wasted disk space generally, which I think should be fixed (if indeed we can be 100% certain that `fmt='%.16e'` is in fact always enough). _______________________________________________ NumPy-Discussion mailing list -- numpy-discussion@python.org To unsubscribe send an email to numpy-discussion-le...@python.org https://mail.python.org/mailman3/lists/numpy-discussion.python.org/ Member address: arch...@mail-archive.com
