Re: [math-fun] when and why was it agreed that 0.999...=1?

Minor correction: I said {.3, .33, .333, .3333, ...} | {} is 1/2 in the surreals. Actually, it is 1. Still reinforcing that {.3, .33, .333, .3333, ...} | {.3+.1, .33+.01, .333+.001, ...} = 1/3 Is the better way to map infinite decimals into surreals.
