It's worth noting, I think, that the java "boolean" data type has rules enforced on it which have almost nothing to do with the mathematical concept of "boolean" (as in "boolean algebra").
Boolean algebras include algebras which work on integers. The java "boolean" data type is really a bit data type with the added constraint that it not be treated as an integer. -- Raul On Sun, Dec 25, 2011 at 11:52 PM, Henry Rich <henryhr...@nc.rr.com> wrote: > Well, Java doesn't use the Iverson bracket, so if they say > > return x > 20; > > it means something different (it returns a boolean).
