Very good calc, i liked a lot. One note only. A lot of times i need to enter values like 0.3, 0.5, etc, that have a 0 before the comma. Almost always because of speed, i don't press the 0, only the comma and continue to the next number. When it is the first number it takes the number normally, like 0.5, but if it is inside the calculation, it takes it like integer, 0.5 would be 5. If you can fix it that, it would be great.
