Burger. For example repr(11./5) now returns '2.2' instead of '2.2000000000000002'. Thanks to noam for the patch! I had to modify doubledigits.c slightly to support X64 and IA64 machines on Windows. I also added the new file to the three project files. ........ r59460 | guido.van.rossum | 2007-12-11 00:00:12 +0100 (Tue, 11 Dec 2007) | 4 lines Patch #1643738 by Ulisses Furquim -- make the is_tripped variable in signalmodule.c more robust. Includes Martin von Loewis's suggestion to set is_tripped after .tripped. ........ r59463 | kurt.kaiser | 2007-12-11 01:04:57 +0100 (Tue, 11 Dec 2007) | 2 lines format_paragraph_event wasn't returning 'break' ........ r59464 | christian.heimes | 2007-12-11 01:54:34 +0100 (Tue, 11 Dec 2007) | 3 lines The new float repr causes too much trouble and pain. I'm disabling the feature until we have sorted out the issues on all machines. 64bit machines seem to have issues and Guido has reported even worse. Guido: It's pretty bad actually -- repr(1e5) comes out as '1.0'... Ditto for repr(1eN) for most N... Both in 2.6 and in 3.0... ........
