  BigInt.prototype.toString ( [ radix ] )

  [...]
  6. If radixNumber = 10, return ! ToString(x).
  7. 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 3.1.4.1.
