check the second attachment, there is a small button there with ... that will
show the button on the gnome calculator.
Either way, inputs like "3E8/3E8" actually result in 1, the problem I guess is
that the button is doing "*10^" and not "e" or "E" and that from the
mathematical sense is not the same.
I just checked Qalculate and they are inserting "e" instead of "*10^", and the
button label is "EXP" and not "*10^y", that could be an option, I guess that
people expect having the scientific notation take precedence even tho it
shouldn't (definitely should't when using *10^).
For now the button is doing what it should, we could change it to be "e", but
let's wait to see if someone else reports the same.
