  3. Let S be a newly created substring of inputString consisting of the
     first code unit that is not a StrWhiteSpaceChar and all code units
     following that code unit. (In other words, remove leading white
     space.) If inputString does not contain any such code unit, let S
     be the empty string
  ...
  13. If S contains a code unit that is not a radix-R digit, let Z be
      the substring of S consisting of all code units before the first
      such code unit; otherwise, let Z be S.
  14. If Z is empty, return NaN.
