, . . "bijective base-26 system". wikipedia:
The bijective base-26 system is also known as base 26 without a zero. It is a base twenty-six positional numeral system which does not use a digit to represent zero; it uses digits "A" to "Z" to represent one to twenty-six.
The number sequence goes A, B, C, ..., X, Y, Z, AA, AB, AC, ..., AX, AY, AZ, BA, BB, BC, ... This is what Microsoft Excel uses to identify columns in spreadsheets.
Each digit position represents a power of twenty-six, so for example ABC is "one 26^2, plus two 26^1, plus three units (26^0)" since "A" is worth one, "B" is worth two, "C" is worth three.
In this representation the number WIKIPEDIA is:
23 * 26^8 + 9 * 26^7 + 11 * 26^6 + 9 * 26^5 + 16 * 26^4 + 5 * 26^3 + 4 * 26^2 + 9 * 26^1 + 1 * 26^0Last edited by Fx_Expo; 26th May 2010 at 14:36.

1, 26, 26 . .
0
0+1 = 1. 26^0 - 1-1=0. .
26.
26+1=27. 26^0 26. 26^1 -> - .
702.
702+1=703. 703-26^0-26^1-26^2=0 - ().
Excel A ZZ 702 . A , ZZ 701.
701.
701+1-26^0-26^1 = 675 () = 25*26+25 = ZZ
1377
1377+1-26^0-26^1-26^2 = 675 () = AZZLast edited by vvvlado; 27th May 2010 at 22:38.
