I've just downloaded the daily snapshot at http://svn.python.org/snapshots/python.tar.bz2

In the header file /python/Modules/unicodedatadb.h, there are the following lines in the changerecords320 struct:  { 255, 255, 255, 255, 1.0 },  { 255, 255, 255, 255, 2.0 },  { 255, 255, 255, 255, 3.0 },  { 255, 255, 255, 255, 4.0 },  ...  { 255, 255, 255, 255, 1e+16 },  { 255, 255, 255, 255, 1e+20 }, Looks like a bug to me.

I don't think so. Unicode 3.2 did contain two entries with large numeric values. The file Unihan-3.2.0.txt contains these two lines:

U+4EAC kPrimaryNumeric 10,000,000,000,000,000 ten quadrillion (American) U+5793 kPrimaryNumeric 100,000,000,000,000,000,000 hundred quintillion (American)

For some reason newer versions of the unicode standard removed these values.
