I was going to tack this onto the thread about pi , but decided that would be a hijack. This site base was cited. Now I know that is a good location to dig up arcane math info, so it wouldn’t surprise me if they’re right and I just don’t know something (quite the admission ), but it says

*A real number x can be represented using any integer number b as a base (sometimes also called a radix or scale). The choice of a base yields to a representation of numbers known as a number system. In base b, the digits 0, 1, …, b-1 are used (where, by convention, for bases larger than 10, the symbols A, B, C, …are generally used as symbols representing the decimal numbers 10, 11, 12, …).*

(it does mention irrational and transcendental bases later - my question doesn’t relate to those). Well, 0 and 1 are certainly integers. How can you represent numbers using 0 or 1 as a base?!
