Minor typos aside, it's interesting that SQLite is nice enough to convert integers strictly less than -1 * 2^63 to floats and then take the floating absolute value.
There are no 64-bit signed integers (which is the only integral type SQLite deals with) less than -1 * 2^63. If you have a number like that, it must necessarily be of a floating point type to begin with. No conversion is taking place.
sqlite> select abs(-9223372036854775809); 9.22337203685478e+18
The conversion here is being performed by the SQL parser, which takes a sequence of characters "-9223372036854775809" and interprets it as a numeric literal representing a floating point number -9.22337203685478e+18 (note loss of precision).
