Hi :)

It takes skill. Didn't Isaac Newton write an entire book, a huge tome of a book too, about "1"?

There is an inconsistency which might be worth writing up as a bug-report except that Excel does exactly the same and is possibly useful to some people.

Also some people on this list might not be ten yet (or do ten-year-olds do trig functions and calculus nowadays?) or those of us that are decades older might be too focused on 'higher planes' and not remember stuff like that from school.

Regards from

Tom :)

Also if you don't bother with any formatting and just use the % key on your keyboard to type in 2.9% then it is shown as 2.9% in the cell and is treated as a number. So, obviously it is wise to do a test-run first to see if you get the result you expect.

Oh man, you just made a very simple thing like percent to look very complicated…

It's very easy, most of us learned about it at the age of something

like ten, maybe earlier in some other countries, I don't know.

Just type 100 into A1, then 2.9% into A2 (LibreOffice Calc will

automatically convert it to 2.9/100 for you, but it still shows up as

”2.9%”, which is the same thing anyway), and finally =A1*(1+A2) in A3

and you'll get 102.9 as a result in A3, simple as that.

If you want it to be even more obvious what's going on, enter

=A1*(100%+A2) in A3. 100% will automatically be changed to 1, though,

so you'll get the same =A1*(1+A2) anyway.

Kind regards
