Ability to calculate with different number systems!
Definitely the best calculator, however it works only for decimal numbers, I would suggest to implement ability to calculate over binary, hex and octal number systems as well as scientific notation option.
At present you can't for example divide or add numbers from other number systems, only for decimal system will work.
Conversion also does not work. for example:
bin(1.22) = bin(0.1) in calculator which is false.
at present only conversion(limited) is possible no operation with different numbers systems.
That way it would become more useful for us developers.
I currently have several calculators in my bookmarks to perform various binary and hex calculations, as well to convert numbers, it would be great to have AIO solution!
