Money Type

Question

Does anyone know of an already implemented money type in the .net framework that supports i18n (currencies, formatting, etc)? I have been looking for a well implemented type and can't seem to find one.

Answer 1

I think you want to use the decimal data type, and use the appropriate overload for ToString().

CultureInfo current  = CultureInfo.CurrentCulture;
decimal myMoney = 99.99m;

//formats as money in current culture, like $99.99
string formattedMoney = myMoney.ToString("C", current);

Answer 2

Check this article A Money type for the CLR

A convenient, high-performance money structure for the CLR which handles arithmetic operations, currency types, formatting, and careful distribution and rounding without loss.

Answer 3

yeah... make sure you use the decimal type for money.

Float is NOT accurate for decimal values.

Answer 4

i would use integer/long, and use a very low denomination like cents (or pence) - then there would be no decimal to work with, and all calculations can be rounded to the nearest cent.

or, take a look at Martin Fowler's book "Patterns of Enterprise Application Architecture". In that book, he talked about how to implement a money class. http://www.amazon.com/Enterprise-Application-Architecture-Addison-Wesley-Signature/dp/0321127420
