radix

   <mathematics> The ratio, R, between the weights of adjacent
   digits in {positional representation} of numbers.  The
   right-most digit has weight one, the digit to its left has
   weight R, the next R^2, R^3, etc.  The radix also determines
   the set of digits which is zero to R-1.  E.g. decimal (radix
   ten) uses 0-9 and each digit is worth ten times as much as you
   move left along the number.
