Schema reports SQL DB mis-match

The Schema module reports a mismatch between the actual DB tables created with install and the ones specified.

Here are the error messages:

* nodemap.nodemap_latitude is type float but its default 0.000000 is PHP type string
* nodemap.nodemap_longitude is type float but its default 0.000000 is PHP type string
* nodemap.nodemap_serialized is type text and may not have a default value

It is not clear to me if I want to change the DB or the declarations in the install page.

MySQL = Server version: 5.0.51b
Mac OS 10.5

Don't see how to edit the SQL in PHPMyAdmin to have a 'precision' => 10, 'scale' => 6.

The length => 10,6 which I assume is the same.

I'd like to get Schema to stop reporting errors.

Suggestions?
