The whole idea of the diagonal argument is that one starts with an infinite list which is presumably exhaustive, i.e. contains all numbers.  The diagonal argument shows that from any such list it is possible to construct a number not on the list, thus proving that the list can't be exhaustive.Using decimals is not very good because it is not clear how you could order the list to be exhaustive.  Use fractions.  First, all in which numerator and denominator add up to 2, then all in which the sum is 3, and so on.  Sure, some numbers will be in the list more than once (infinitely many times, in fact) but the point is that this constructs an ordered list of rational numbers.  After ordering this way, one can write the decimal expansion then use the diagonal argument.> Herc> --Note that the RFC specified a space after "--" for the .sig separator.
