In Python, any floating point number is stored as a
Double Precision Floating Point. i.e. "double" in the
underlying C language library. Typically 8 bytes.

1.2 won't use more space than 1.21212121212121

What do you mean by database in this case?

SQL databases typically have data types where
you can define how many decimals they should
store. The database adapter will take care of
conversion between Pythons float format and
the format defined for the database.
