I'm running into some of the very problems you mention.
I tried "Decimal" as the field type, but 100.5 gets rounded up to
101.00...not good.

I tried Integer, but when, for example, 100.50 gets entered into a
formfield,
then inserted into the db, it gets truncated to 100.  How do I set up
Integer
to retain 2 decimal places?

Also, I'm trying to setup the mySQL db fieldtype and CF processing such that
if a user inputs $100.50, which is not a number, mySQL won't reject it.
I tried setting up the CF input line with various combinations of functions,
such as:

<cfqueryparam cfsqltype="CF_SQL_INTEGER"
Value="#LSCurrentFormat(LSParseNumber(Form.UCPaymentAmount))#">

but I haven't been able to find the right combo to allow users to input
either 100.50, 100.5, or $100.50
and still get the right number into the db without rounding or truncating
and back out for display on the CF page.

Clues?

Rick

Integer is the safer way to represent money - as pennies - because that
way you avoid rounding errors. Financial applications should never use
floating point to represent dollars (or whatever). If you take 0.00 and
add 0.01 a hundred times, you're quite likely to get something which
does not equal 1.00 because of inherent inaccuracies in floating point
representation.
