Hi

This is interesting.

Are you using the sqlite3 wrappers?

Are you trying to get a large signed integer from a database query, or as
a return value from one of the other functions?

The reason I ask is that database queries are returned as text values in
sqlite3,
so you have to do the conversion afterwards.

However, if you are using functions not yet wrapped in eusqlite3, and you do
manage to wrap them, I would be more than happy to add them to eusqlite3
library.
