Not sure what that means, but there's no question you should use BigDecimal to represent a decimal value like money. Or to put it another way, there's no conceptual reason to use a Float for this. :-) > I've done some testing and the error doesn't appear when just outputting > the value in a view.

That helper is apparently using the supplied input values as numbers to generate the graph. Trying to turn a value into a String at that point is definitely going to cause the failure you're seeing. If you want a decimal number like "100.00" to /display/ in the view, I think you'll need to change the helper. Bummer that there don't seem to be any tests for it.
