Yes, of course.

Why stop there? The square roots are numbers too, so *their* square roots should be even shorter. But then the square roots of the square roots of the square roots would be shorter still.

Yes, very good compression is indeed possible. If yours is better than the schemes used to date, you should publish it. -- Ben.
