Integer math =  Currency or in  DB numeric(18, 4)

in Firebird
create domain AMOUNT as numeric(18,4);

Yes i do that from more than 10 years, Float/Extended have problem when
rounding it and sum that rounding, it is only good in Science not

Currency for me is  Int64 (* int of 10000 or binary shifted) it is more
stable and not lose any cent when sum the balances, until i passed it to
ABS, ABS convert it to float and return back to Currency, that my problem

In the future i like to have new kind of Currency (integer) but more extend
(* 1000000 for example).
