|#30||fixed||Timestamp support has floating-point roundoff||xi||edemaine@…|
>>> import yaml, datetime >>> yaml.dump(datetime.datetime(2005, 7, 8, 17, 35, 4, 517600)) '2005-07-08 17:35:04.517600\n' >>> yaml.load(_) datetime.datetime(2005, 7, 8, 17, 35, 4, 517599)
This breaks the desired rule that yaml.load(yaml.dump(x)) == x in a case where there should be no roundoff. (datetime.datetime uses integers everywhere to avoid any error.)
The offending code seems to be line 321 in yaml/constructor.py:
fraction = int(float(values['fraction'])*1000000)
This seems to be an "easy" way to convert the trailing '.517600' into an integer, but it can go beyond floating-point precision. Wouldn't the following work?
fraction = int(values['fraction'][:6].ljust(6, '0'))

Could you compile a Windows binary of PyYAML for Python 2.5 (released fairly recently)? Ideally with libyaml support built in...
