Frequently Asked Questions

Why doesn't Hextrapolate let me type the characters I want?

Hextrapolate only allows you to enter characters that are valid for a given base (when typing in a number field) or which can be encoded losslessly in the selected text encoding (when typing in a text field). The list below shows the characters which are legal for the most common bases:

Base 16: 0 1 2 3 4 5 6 7 8 9 a b c d e f
Base 10: 0 1 2 3 4 5 6 7 8 9            
Base 8: 0 1 2 3 4 5 6 7                
Base 2: 0 1                            

One of the reasons Hextrapolate does not support bases greater than Base 36 is that this is the highest base that can be represented using the 26 letters of the Roman alphabet (a-z) in tandem with the numerals 0 through to 9. If we were to introduce a distinction between lower and uppercase letters then we could theoretically go as high as Base 62.
