It is the result for 0.05 that is more surprising than the 
result for 0.07.

You wrote your numbers using decimal ".05" or ".07" but most computers
these days are binary machines.


What I found surprising was the lack of consistency rather than the
number of decimals shown in the result ...

7 is the only number that produces a result with many decimals...
I would expect all the numbers behave that way or to behave in the 
other way i.e. only a couple of decimals... but I didn't expect it
to behave in a different way depending on the number.

7 is the only number that shows that behaviour. I tried all the others,
2,3,4,5,6,8 and 9 and only 7 behaves that way...

I guess I'll have to start using format-number when the number is 7. ;-)
