I have a field which contains values like 3.7, 4.2, etc. But when I
defined the field (in SQLite) I made it a TEXT field, forgetting that I
would need to be able to sort on that field.

My workaround is to convert the string to floating at the time of the
sort. In SQLite I do:

... ORDER BY ROUND(myfield,1);

which works just fine. Richard should look for something similar in
mysql.
