No, they are extended float that are munged and masked to have a kind of
exact precision and scale for display and calculation purposes. I think
Geoff talks about it in his article. Delphi/ObjectPascal doesn't have any
scaled numerics. I gather from Chad Hower's message that .NET has a
decimal type.

You should read the Delphi help. I've already described the differences
between fixed and floating point types in Firebird.
