Hi all,

I noticed that the output of the eval() function is related in some way to the decimal places setting... Don't know if it's a bug or a feature, but seem it's not a rule (see the screenshot)
IMHO it's preferable to cancel this behavior...

best regards,

I might not quite understand your point, but I think this is a matter of rounding to some number of decimal places and it is ok with me when I put 1.05 and us 1 decimal place to see: 1.05=1

Sorry, Davide - I do not get it

And where all those fractions come from. I delete them, press equal to - and got the fixed/exponential numbers

Maybe I'm wrong in my first post, but I don't understand from where the values in the red boxes comes

Ah that ...

Like I was blind, I did not pay attention on this

I just hope that this is only in presenting the numbers, and should not influence on some calculation behavior - I hope

The trouble comes from the fractions setting in the context menu and how it is processed.
If you switch to decimal, then everything is fine. Default setting is "auto". If set to "fraction", then odd fractions are generated, which are far from minimal (or just correct) representations of the given number.

Also, for more clarity, I switched on the display of trailing zeros.

EDIT: line 8 is same as line 7, sorry, but you still get the point...
