Actually, I'm interested in this function because I'd like to modify it to use an arbitrary character table. Base 46 including all URL compatible "non-reserved' characters including the symbols " - _ . ! ~ * ' ( )
Consider how TinyURL or YouTube urls are constructed, but utilizing all of the valid symbols in a lookup table.

It is still just two lines for unsigned numbers | Code: | ToBase(n,b) { ; n >= 0, 1 < b < StrLen(t), t = digits
Static t := "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_abcdefghijklmnopqrstuvwxyz{|}~"
Return (n < b ? "" : ToBase(n//b,b)) . SubStr(t,mod(n,b)+1,1)
} |
Change the static variable t to contain your desired digits in order. |

It's just a translation of the elementary school routine you're already familiar with. You must have a relatively deep understanding of AHK to figure it out though. |
