The tests are there to proof that it parses doubles correctly. The algorithm 
can be treated as a black box. It doesn't need to be exhaustively checked, that 
has already been done far more thoroughly than we can hope to do -- it's like 
having to prove that some complex sorting algorithm works; you don't need to 
fully understand the algorithm, just verify some edge cases, to proof you 
didn't make a mistake "copying" the proven algorithm.

I checked what Michael copied, and I didn't see any mistakes. The test cases 
(and probably numerous dependent tests in the rest of FX) proof that it works.
