Interesting question. The rationale for the current setup is that there is no
infinity for Integers (nor NaN) so exception is the only option; whereas
infinity is an option for doubles and while we can argue about the absence of
overflow exceptions in Java, returning Infinity on double overflow is
consistent with the Java language spec (4.2.3).
