--- Comment #5 from IanS <MyBugzilla at mailinator.com> ---
On Windows I get the same output as you.
But on my Wine/Linux box I get

//       '1,643.57' --> 1643.57
//       Unable to parse '$1,643.57'.
//       '-1.643e6' --> -1643000
//       '-168934617882109132' --> -1.68934617882109E+17
//       Unable to parse '123AE6'.
//       Unable to parse ''.
//       '' -->                           // Weird //
//       Unable to parse 'ABCDEF'.

Something really strange going on. '' --> shows that it parsed successfully but
the number is missing.

But. Strangely, even though the number is missing it's possible to do something
like:

if(number > 5002)
   MessageBox.Show("number is bigger than 5002")

Actually comparing the double with 5002 in my app is where I notice the glitch
in the first place. Even though the double appears to be empty it still has a
value bigger than 5002. I wonder how bit it is?
