hi,
even weekend went off nevertheless this subject is still interested (=
I think now about that mathematics has "global failure" in the whole.
Here is a riddle. We all had scholl and teachers says as that "a/a=1". So 3/3 should be 1.
Okay, let me calculate it myself.
First of all, I write it with different way:
3*(1/3);
Is it still one? mathematics fraction theory says "yes".
Now I calculate it manually:
1/3 = 0,33333 [period]
Now I multiple it with 3:
3 * 0,33333 [period] = 0,99999 [period]

Now the question:
is 1.00000 [period] the same as 0,99999 [period] exactly? I doubt...

So where this a very-very little part of number come out to? Maybe is it a payment to Universe for our brains? (=
Another point: maybe is this very-very little difference is that thing we call ZERO?

Regards,
Oleg
