Thanks, I will check the newer version.

For a couple of applications writing and reading numbers as strings is 
simply too slow. So, you store them in binary format. But as I wrote the 
application I know how I stored them (on all platforms).
Therefore, using the number type instead of a string for the validator 
makes sense.
