base26
Base26 refers to a numeral system that uses 26 distinct symbols, typically the letters A through Z, as its digits. In general, a base-b system represents integers as sums of powers of b with digits ranging from 0 to b−1. When the symbols are letters, base-26 is often used for labeling, encoding, or compact alphabetic representations rather than for arithmetic in the usual sense.
There are two common conventions. Zero-based base-26 uses the 26 digits 0 through 25, which can be
Conversion to bijective base-26 involves repeatedly subtracting 1, dividing by 26, and mapping remainders to letters.
Applications include labeling schemes, such as spreadsheet columns, inventory codes, and simple alphabetic encodings. Base-26 is
