Precision and Scale?

Hello,

I have been trying to develop an automatic way of programmatically accessing datasources and performing some predefined(-supported) processing on them.

The question I would like to ask you people has to do with numeric fields. What exactly is precision? Is it the maximum length in digits of a field, or is there more to it? What about a "field's scale", what is it and how does it affect a field's value handling?

Thank you very much,

Dave
