  radix
  
      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.
