I don't think you should roll out your own math engine.

Example, if I press
65 / 9 =
* 9 =
it tells me the result is 63.

Compare to kcalc that properly tells me 65.

You can't really use C/C++ floating point to do actual math, it's not very good for \
that, you need to use "infinite" precision numbers like kcalc does.

Please reconsider your decision.

Besides that tou need to make more things translatable, Sin, etc.

Cheers,
