  Letters a-z are used for digits with values 10 through 35
info: |
  6. Return the String representation of this Number value using
  the radix specified by radixNumber. Letters a-z are used for
  digits with values 10 through 35. The precise algorithm is
  implementation-dependent, however the algorithm should be a
  generalization of that specified in 6.1.6.2.23.
