calculator's Issues

Calculator makes the sum of the two previous numbers before multiplying

I tried out the calculator and I figured out when you do (3+3*3), your calculator adds the 3+3 as soon as you click multiply (this should only happen when + or - is clicked for the second time, not * or /). This results in the answer being equal to 18 instead of the correct answer, 12.

Does not calculate the percentage after addition or subtraction or multiplication or division

When i add (subtract, multiply or divide) two numbers & try to get the percentage of it, the calculator does not display the percentage value. For an example these are the steps i followed

1. click 3
2. click +
3. click 4
4. click =
5. click %

This shows the output as 7

I'd would like to help out with this issue

The leftmost zero in a number

When start clicking number buttons everything is ok, but if I start number with 0 this zero remains, while it should be overriten by the next non-zero number :)

doesn't support key presses

it would be great if this calculator support keypresses because it will reduce unnecessary mouse moves and clicks

The site is not up to date

ahfarmer.github.io/calculator is not up to date. The site shows a calculation error. This is what i found.

When i click the multiply button twice after entering the value, the output shows as 0

Not showing percentage result

Paste below code into calculate.js file

operation: null,
};
} else {
// '=' with no operation, nothing to do
return {};
}
}

`

Issue will be solved and show percentage result

Numbers are padding off the screen

If you type or calculate a really large number (ex. 10000000000000000000), it gets out of the screen

How hot is updated

Modulus (%) operator is not working with two numbers

The % operator is always doing operation with 100 only .It should be do operation like other (+,-,/) operators are doing .

Issue with Regex in isNumber.js

The regex written is /[0-9]+/
It would return true even if there are any other characters in the string.
If the regex is /^[0-9]+$/, it specifies there should not be any characters other than numbers.
Please look into this.
