ExE - GoogolTeam/googol GitHub Wiki

ExE, short for the Extensible-E System, is a notation for large numbers created by Sbiis saibian. this notation has various stages: Hyper-E Notation (E#), Etended Hyper-E notation (xE#), Cascading-E notation (E^), Extended Cascading-E Notation (xE^), and Hyper-extended Csacading-E notation (#xE^).

The rules of xE# are shown below:

1. En = 10^n

2. @#...#1 = @

3. @b#...#p (n #s) = @b#...#(n-1 #s)b#...#(n #s)(p-1)

4. @b#p = @(@b#(p-1))

This calculator also provides the letters A, B, C, and D to change the the first rule, from 10^n to 10*n for B or D, n^10 for C, and n+1 for A. All other rules are the same.

You can also use nonintegers, in which case it will interpolate between the nearest integer cases. (Note that B and D have different interpolations.)
