Re: Decimal versus Float Point Type

Sorry, I should have added more smiles, it was supposed to be a joke about
the dollars... ;)

But still, I could win a lot of money by distributing people's money to
their three kids and getting 1 cent out of every operation. :D

What I tried to say (and probably failed miserably) was something close to
what you said about "what is your model" but giving a pratical way of
finding out if the data type will fit your model or not.

In number theory, a set of operations is what define the model of a number
sequence, so at the end, we said exactly the same thing, but in a
different way.

Glad you completed my observation! ;)
