So I've got a ruby on rails code which use float a lot (lots of "to_f"). It uses a database with some numbers also stored as "float" type.

I would like to migrate this code and the database to decimal only. Is it as simple as migrating the database columns to decimal (adding a decimal column, copying float column to decimal one, deleting float column, renaming decimal column to old float column name), and replacing "to_f" with "to_d" in the code? Or do I need to do more than that?

Thanks a lot everyone Raphael
