      You're fortunate, next year will leap. Not sure yet whether you'll get a day without confusion, or just a bonus. :)

        For the most part, yes. There are some things that work in some bases, but not in others, even in some complex bases. A hexadecimal representation of pi was discovered a while back, but no decimal representation is possible (I think).

        Nope. Either your memory, or the person who told you that is mistaken. Pi is an Irrational number[^], which means it's been proven to be impossible to write in the form a/b; which makes it infinite and non-repeating in any base.

          According to this[^], "For centuries it had been assumed that there was no way to compute the _n_th digit of π without calculating all of the preceding n − 1 digits."

            There are still an infinite number of digits; it's just that in base-16 any one of those digits can be calculated without calculating the others.

                Other than (arguably) being prettier, there's nothing to make that representation better than any of the other formulas.

                  So there I was, wallowing in the bath when it suddenly occurs to me 'would maths work the same if we used a different base.' What I mean is, lets say instead of the 10 fingers that we have and on which our decimal counting system is based we had say 14 fingers so we would be counting in base 14 as the norm. Would things like Pythagoras theorem, the Fibonacci sequence, Pi, prime numbers, calculus, square roots, sins, cosines and tangents work? Not being a mathematician, I can't get my head round whether these would work or not. Intuition tells me it would. Would this work in base 14? http://news.bbc.co.uk/1/hi/sci/tech/2911945.stm[^] Does Riemann's hypothesis work in any base? What do the great and good think?

                  Mathematics is not a science of numbers, but rather a science of the relationships among numbers. In fact, it can be boiled down to relationships, period. Numbers happen to work well as a common coin, but mathematics works as well for notes in a musical scale. You can rotate, translate, change base, or work with the hyperbolic cosine of the symbolic representation of a relationship, and it will all work out the same. But you might be making it a lot harder for yourself. A change of base is often used to make a job easier to do, without changing the underlying principle. Try building a decimal computer some time. It can be done, but it can't be done conveniently or cheaply, as a device that can operate on ten states is a lot more complex and expensive than one which is stable in only two states. The result is that we have binary computers for economic reasons. As programmers, we use hex and octal representations sometimes, but that's to make our jobs easier on our brains; the computer will always translate our products into binary before processing it, then it will change base again to make the result easier for us to understand. The math remains the same.

                    Yes. The numbers themselves aren't base 10; we just use base 10 to communicate with each other about them.

                      I don't see why not. Surely the base is just the way that the number is written down and doesn't change any of the calculations etc?

                        Again, it allows for calculating any digit of PI in base (2 or 16) independently of all other digits. No other base has that.
