Error in percentage calculation
What Happened?
When performing an addition or subtraction operation with percentages, the program ignores that it is a percentage. For example: 100 + 2% = 100.02 (the correct would be 102). 100 - 2% = 99.98 (correct would be 98)
This happens with any number you type.
Steps to Reproduce
- I opened the calculator from "Applications".
- I typed the numbers from the keyboard, including the symbols.
- I get the wrong result.
- I enter the values and symbols from the calculator program itself.
- I persist with the error.
Expected Behavior
Basically because it is expected to operate with percentages, but what it seems to perform is a decimal operation.

There was a PR (#137) suggesting a way of dealing with this but it did not get any traction at the time.
Without this function it's completely useless for me, Elementary you can remove it from the OS, I have to use another one.
Duplicate of #44. This is an old issue for which no universally acceptable solution was found due to the ambiguity of the % operator (which the project leaders would prefer to be ignored altogether).
Looked at how Google handles this - essentially it does not interpret % as the mod operator. If you enter a % b then it interpolates x to give a% x b. If you enter a + b + c% it gives a + c% x b. It should be possible to emulate this behaviour. Calculator does not seem to implement mod anyway.
Correction, Calculator recognises mod as the modulo operator (but not %%)
@EnriquePG-Noc, @Dragonfir3 I have pushed a PR to address this - #268. If you are able to build and test this I would welcome your comments.
