Just checked. Yes, apparently Microsoft ODBC drivers format money with
4 decimal digit.
I think in the past tools used 2 digits but they moved to 4 along the way.
There's actually no way to change that behavior but probably there should be.
The 2 digits code is currently quite hard coded in src/tds/convert.c
and src/tds/numeric.c.
I suppose a good way would be to add a flag to TDSCONTEXT (which is
used during conversion to pass locale information).
