quote:Originally posted by Atomic-SThis forms a rather unusual number.

quote:An irrational number (i.e. one which cannot be expressed as a ratio of two integers) has an "aperiodic" decimal expansion – i.e. if written as x.xxxxxx... then the digits after the decimal point go on forever and never repeat in any sort of pattern. (So pi, e, sqrt(2), etc, when written as decimals, have an infinitely long sequence of numbers after the decimal point that appear "random" and never settle into any sort of periodic pattern.)

quote:Originally posted by Atomic-SWhat about sum, n = 0 to infinity, of n/10^{n(n+1)/2} ? Those digits look highly aperiodic to me, but are far from random.
