Pure vanilla JavaScript calculator using modern ES6 syntax and classes

vanilla-javascript-calculator's Issues

Line 19 is missing .toString()

`if (number === '.' && this.currentOperand.includes('.')) return`  

should be
if (number === '.' && this.currentOperand.toString().includes('.')) return

otherwise, appending a dot is not possible after a equalsButton compute()

Negative number as first input

I noticed that the calculator cannot process negative number as first input.

I tried to built the feature, but after hours and hours of trial and error, i yield.
this task is beyond my scope of understanding, i someone with more experience
try to built it ?

it would really help me an others that recently learning to code and want to dive deeper
in the universe.

adding keypress

I want to add keypress in the calculator. so that if someone presses numbers from keyboard also it should work.
Please assign me this task so can i start working on it.

how to add calculation history feature?

how to handle the divided by Zero case.

Change the Previous Operation to New Operation

When we have selected an operation to Compute the result we can't change it to another Operation. The only way is to either clear or evaluate.

Steps to Replicate the issue

1. Add any Number Input
2. Select any operation (say +)
3. Try to change the operation ( we can't change the + to any other operation)

Dividing Zero by Zero breaks the calculator.

When I divide 0 by 0 it breaks until I press AC. Dividing 3 by 8 gives infinity but 0 by 0 gives nothing and it stops working.

It didn't work

Unexpected identifier

const numberButtons= document.querySelectorAll('[data-number]')

Don't able to use . after calculation

wrong results

0.1 + 0.2 and dividing by zero are giving the incorrect result. I know it is a JS fault, but I was hoping to find a solution here.

Calculator won't work after deleting a digit from a number

Divide by zero solution

case '÷': if(curr == '0') { compute = '0'; } else{ compute = prev / curr; } break;

Cannot add an error message because for divide by zero as we are using getDisplayNumber() method to edit current operand. Hope this works
