Funny, I used the exact same example to prove that o.99999... was NOT equal to one. I was criticising maths for the very fact that 0.9999... is equal to one. After thinking over my statement, I realise it most probably is 1. But try to visualise this and there's just this annoying missing link. Oh well. P.S. so does 0.1111... = 1.11111... This is silly. infinity bugs me!
