Hi B,

I don't understand your comments here. For example, you say:

I don't understand what you mean by "crossover", but more importantly, I 
don't understand your comment about 0.3. Gnumeric already rounds down:

    0,30000000000000004

to 0.3 (displayed to 16 decimal places). Of course the true value is:

    0.29999999999999998889776975374843459576368331909179687500000000000

but that will be displayed as 0.3. So I'm not sure why you seem to think 
that Gnumeric is not already doing that.
