sqlite

Hello,

I'm using SQLite to store some data. The primary database is on a NAS (Debian Lenny, 2.6.15, armv4l) since the NAS runs a script which updates the data every day. A typical "select * from tableX" looks like this:

2010-12-28|20|62.09|25170.0
2010-12-28|21|49.28|23305.7
2010-12-28|22|48.51|22051.1
2010-12-28|23|47.17|21809.9

When I copy the DB to my main computer (Mac OS X) and run the same SQL query, the output is:

2010-12-28|20|1.08115035175016e-160|25170.0
2010-12-28|21|2.39343503830763e-259|-9.25596535779558e+61
2010-12-28|22|-1.02951149572792e-86|1.90359837597183e+185
2010-12-28|23|-1.10707273937033e-234|-2.35343828462275e-185

The 3rd and 4th column have the type REAL. Interesting fact: When the numbers are integer (i.e. they end with ".0"), there is no difference between the two databases. In all other cases, the differences are ... hm ... surprising? I can't seem to find a pattern.

If someone's got a clue - please share!
