For Java specificallly, it can't be in the compiler since it would no
longer be Java. However, you could easily have a FixedPoint class which
implements Number and use that. Since Java doesn't support operator methods
you have clunky syntax like a=b.multiply(c) etc, but it works.

I'm not sure exactly what you are referring to. Floating point and fixed
point each have their proper place. Personally, what I want is an
environment flexible enough to accomodate what each person wants and
modular enough to do it without negatively impacting people who don't
want it.
