in thread Alpha base-26 to base-10...

I know it's been years since the last post on this but I came across it in dealing with the same situation. I'm not seeing how "base27 with no defined symbol for zero" really describes this numbering system either. For example, the 27th integer (if that term really applies here) in the "MS Excel" system would be AA. "AA" in a base27 system would be the 28th integer. Maybe we should call it a Mayan base26 since their base6 system didn't have a zero either (because they never discovered it).

    We're all going to hell for resurrecting a dead thread, but how do you do double digits without a zero? Still, I think you've got the right idea. The alphabet is best used as a base-26 system, with A as zero. So AA would be the same as A. Z is 25, BA is 26, and so forth.

    Now I'm curious to see how the Mayans did math...
