type: 5
flags: 7
width: 5 (make it 6 bits and signed)
base: 5
precision: 5 (make it 6 bits, and signed)
qualifier: 3

Now, admittedly, right now 'qualifier' really has to be 8, but that's just 
because we use an ASCII character for it. But I don't think there are more 
than 8 actual legal qualifiers. And 'base' could be just 2 bits, since 
there are only a couple of legal bases, but I left room for them all 
anyway.

And the other really should fit in those numbers unchanged, I think.
