I had a class today which dealt with Decimal <-> IEE754 conversion,
and
whilst 0.1 was an example that was converted, and a representation was
generated, no mention was made of the precision issue.

I'm hoping that it was just that we ran out of time, and the lecturer
will discuss it in detail next time.
