Various country's "currency decimal places width" in the iPhone-SDK

Question

I read about NSLocaleCurrencySymbol, but where would I find the variable used to determine the "number of decimal places" used in a country's currency?

I.E. In the USA, it's common to see dollar amounts written with 2 decimal places: $1.23

What about many other countries?

Thanks.

This has much of what you're looking for.

Answer 2

There are a number of other countries that display a different number of decimal places. 2 is the majority, 0 (no cents in their currency, e.g., Japan) is the largest minority, 3 is used in just a few. No other number that I know off. When exchange rates are quoted, more decimals are typically used. The currencies with 0 and 3 that I'm aware of are shown below.

The ISO currency codes can be found here: http://www.iso.org/iso/support/currency_codes_list-1.htm
