Thank you very much, Duncan! Now it is totally clear for me. Reading the 'R
inferno' tract suggested to me in private by a user (nut one can google it),
and wondering about heaven and hell....
Best regards, Z

I'm glad you are happy with your solution. Just one inline comment below,
expanding on my private reply to you:
No, that's not how standard floating point representations work. 12.34 is
represented as a finite precision binary number between 1 and 2 (starting
out as 1.10001 in binary notation) multiplied by 2^3. The problem is that
there is no way to represent it exactly in this format. Only fractions with
a power of 2 in the denominator can be represented that way, and 12.34 is
not one of those. It's 1234/100, and 100 is not a power of 2.
