At our roots, aren't we all a little irrational?

So R__>__0, the Non-Negative Real number set, is joined by, R, the Real number set; N, Natural numbers; Q, Rational numbers (R was taken); Z, Integers (don't ask); P, Primes; and C, Complex numbers.

I also saw a notation for H, denoting Quaternions -- I didn't even go there. Except to note that Q was taken already because R was taken already.

And O for octonions, which H is a subset of.

:)

Q comes from "quotient": Z comes from the german word "Zahlen": there's also A for the set of algebraic numbers....

And H, of course, is for Hamilton, after the guy who discovered quaternions.

Of course, I had an entry for that!
