Alex Martelli	d8672aa8a4	Fix compile.c so that it records 0.0 and -0.0 as separate constants in a code ... object's co_consts tuple; add a test to show that the previous behavior (where these two constants were "collapsed" into one) causes serious malfunctioning.	2007-08-22 21:14:17 +00:00
Alex Martelli	348dc88097	Reverting the patch that tried to fix the issue whereby x**2 raises ... OverflowError while x*x succeeds and produces infinity; apparently these inconsistencies cannot be fixed across ``all'' platforms and there's a widespread feeling that therefore ``every'' platform should keep suffering forevermore. Ah well.	2006-08-23 22:17:59 +00:00
Alex Martelli	20362a820b	x**2 should about equal x*x (including for a float x such that the result is ... inf) but didn't; added a test to test_float to verify that, and ignored the ERANGE value for errno in the pow operation to make the new test pass (with help from Marilyn Davis at the Google Python Sprint -- thanks!).	2006-08-23 20:42:02 +00:00

Michael W. Hudson	ba283e2b7f	This is my patch: ... [ 1181301 ] make float packing copy bytes when they can which hasn't been reviewed, despite numerous threats to check it in anyway if noone reviews it. Please read the diff on the checkin list, at least! The basic idea is to examine the bytes of some 'probe values' to see if the current platform is a IEEE 754-ish platform, and if so _PyFloat_{Pack,Unpack}{4,8} just copy bytes around. The rest is hair for testing, and tests.	2005-05-27 15:23:20 +00:00
