Hi Ohlbe,


» Mmmm. But then if the problem comes from the nasty 0.1, how comes that if I type =(0.8-0.4-0.2-0.1-0.1) I get a nice 0, without any funky E-17 ? And then if I type =0=(0.8-0.4-0.2-0.1-0.1), or =0=0.8-0.4-0.2-0.1-0.1 I get a nice TRUE ?

Impossible to tell if this is an effect from Excel or from some degree of streamlining within the CPU.
It is fairly trivial (I think) at the CPU level as well as in Excel to check if you are handing objects of the type (x-x) and to substitute those with a zero where they occur.

Pass or fail!
