Re: Money casting too liberal?

In the bad old days when I was a COBOL programmer we always stored money in the COBOL equivalent of an integer (numeric without a fractional part) to avoid round off, but we displayed with a decimal point to digits to the left.  So storing as an integer (actually bigint would be required) is a good idea, with parameters to say how many effective digits in the fractional part, and how many fractional digits to display etc. - as you said.

COBOL Numeric was BCD.   same as NUMERIC in SQL (yes, I know postgresql internally uses a base 10000 notation for this, storing it as an array of short ints, but effectively its equivalent to BCD).
