You made a definite false statement, and no subsequent qualification
negates that.  A skilled author would have put that statement last,
preceded by "Otherwise", or similar; or would have used "will generally
return".


But I must apologise; it was at least _quadruply_ untrue.


Who can list four or more distinct cases in which Number(myString) will
**NOT** return NaN although there are non-(digits or dots) in myString,
ignoring leading and trailing whitespace?

That was to amuse the more intelligent, and to inform those unaware of
Unicode i-xii I-XII characters.  You should have ignored it.
