Fixed point decimal for one.

I don't think core C has a such a concept. I'm pretty sure that the early versions of Java didn't have such a concept either. In fact, the support it currently has are not native implementations ... they are Objects (BigDecimal).
Exactly, David. And in fact the BigDecimal implementation in core Java performed so poor initially that IBM created their own; you had to choose between them. And to this day, BigDecimal still has issues; you can't simply add to a BigDecimal; you have to reassign it to itself:

BigDecimal bd = new BigDecimal(1.1);
bd = bd.add(3.4);

I realize this is to allow chaining of operations, but even that is evil:

BigDecimal tax = quantity.multiply(unitprice).multiply(taxrate);
