We just need to accept what we are told and get on with using it as before. Forget about the egotists trying to make a name for themselves. It gives perfectly usable results:sh rug:!

Saying that pi does not exist because it requires an infinite decimal expansion is on a par with saying sqrt(2) doesn't exist because it requires an infinite decimal expansion. They just happen to be irrational numbers and as was long ago proved by Cantor, such numbers vastly outnumber the rational ones, ie those that have a finite decimal expansion. I realise some of these statements my appear a bit vague, but I'm trying to be brief. Have a look here if you want the real version.
