Re: [webpayments] Expression of monetary amounts (#40)

> Developers using ISO8583 have managed for some decades as I say. There is a finite set of global currencies and knowing how to convert them from minor currency to a decimal if required is pretty easy to accomplish. Any new currencies like Bitcoin have to define what their minimum unit of account is and anyone using that currency can fairly be expected to need to know that.

Can ISO8583 support payments with a fractional part of the standard minimum unit of account?  For instance USD $0.0005 or USD $1.005.  Such a feature would be useful for micropayments or other exact precision payments.  This may not be a common use case, but would be nice to to make it possible at the protocol level.
