A Noble effort; thank you very much!
But, alas, it demonstrates _exactly_ the problem I expected.

The radix = 17 was a nice touch :>, but certainly, given the bigfloat 
defn, several applications will be perfectly justified in exporting 
bigfloats w/ radix=16, and I probably wont have any control over it.

So, I can expect my Live Math documents to look like this:

  "The first zero of the Airy function, a_1, is at
         a_1 = -160673517802x16

Am I the only one that has a problem with this?
