New submission from Vernon Cole <vernondc...@gmail.com>: I am making a demo program, a class which is a subset of int, which implements a partial implementation of PEP313 (Roman numeral literals).
I discover that my conversion routines fail for values > 50000 due to an error in unicodedata for the two code points 2187 and 2188. The return value of unicodedata.numeric() for those two points should be 50,000.0 and 100,000.0 respectively. See the following console dump which includes code point 2181 which works correctly. ----- console dump follows ----- c:\BZR\roman>c:\python26\python.exe Python 2.6.2 (r262:71605, Apr 14 2009, 22:40:02) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import unicodedata >>> unicodedata.name(u"\u2187") 'ROMAN NUMERAL FIFTY THOUSAND' >>> unicodedata.numeric(u"\u2187") Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: not a numeric character >>> unicodedata.name(u"\u2188") 'ROMAN NUMERAL ONE HUNDRED THOUSAND' >>> unicodedata.numeric(u"\u2188") Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: not a numeric character >>> unicodedata.name(u"\u2181") 'ROMAN NUMERAL FIVE THOUSAND' >>> unicodedata.numeric(u"\u2181") 5000.0 >>> ---------- components: Unicode messages: 89899 nosy: vernondcole severity: normal status: open title: error in unicodedata.numeric(u"\u2187") and 2188 type: behavior versions: Python 2.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6383> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
