Well done, looking great.
- replacing the operator with a zero can be confusing to the user, maybe keeping the operand or displaying the operator to the screen
1 + 1
will give you the correct result2
but to continue the operation from there will start giving you the wrong results.- When entering a floating number, the
dot
does not show until you press a number. That's confusing as some users will think that the dot is not working. - I cannot enter a floating number with more than 5 digits with some rounding happening during data entering
