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.
