[Seaside] Magritte MANumberDescription and ScaledDecimal numbers

[GMailAccount]

I'm having a little trouble with MANumberDescription, because it keeps
internalizing the numbers as ScaledDecimals, and for whatever reason,
ScaledDecimals print out like this:

0.05s2  0.0s1   15s0
0.05s2  0.07s2  44.0s1

etc.

This is really going to boggle the users minds, and I know I'll get  
asked
weekly: 'What are the S's for on those numbers?'.

So ideally, I'd like MANumberDescription to treat the numbers as Floats.
Alternatively can the rendering methods for MANumberDescription can be
overridden, to preform the necessary display conversion  
automatically? Or is it
best to directly modify the ScaledDecimal class to print the way I'd  
like?

Cheers,
