None of them is using a fixed precision: they're all using David Gay's implementation of the "shortest string" algorithm (à la Burger and Dybvig). For repr, this is the case since Python 3.1 / 2.7; for str and formatting with no type specifier, since Python 3.2. The docs definitely do need updating here. > I expected this last to be > '33.14159265358979' '33.1415926535898' is shorter, and rounds back to the same floating-point number, so that's what Gay's algorithm gives here. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22546> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
