[Sussex] Challenge

[Geoff Teale]

Morning all,

Seems a long time since anyone has set a challenge to get Nik and Mark
thinking and make Jon complain about the prominance of mathematical debate
amongst list members.

So here's one...

Computer scientists often say that 10 times 0.1 very rarely equals 1.0   All
I want you to do is come up with a wholly accurate binary representation of
the number 0.1 that can be used by normal floating point operators without
the use of "fudge factors".  The proof is simple, it must in base 2 prove
that the following base 10 equation is correct:

10 * 0.1 = 1.0

.. most convincing arguement wins the notional pint - should Pip win (most
likely as she is often the only person to walk away from a LUG meet with her
intellect untarnished) a non-alcoholic prize may be allocated ;)
