Javascript question

Question

I wanted to create a quadratic equation solver but I stopped here.Who can help me to find my mistake:

let a=prompt("Give value for a")
let b=prompt("Give value for b")
let c=prompt("Give value for c")
let d=confirm( Math.pow(b,2)-4*a*c)
if(d>0)
alert((-b+Math.sqrt(d))/2 * a)
alert((-b-Math.sqrt(d))/2 * a)

Answer 1

parse the inputs from the prompt as int, otherwise a, b, c and d will all be Strings...
so:
let a = parseInt(prompt("Give value for a");
...

what errors are happening? Is it an logic error or an runtime error? 😅

Answer 2

or parseFloat() would actually make more sense ...

Answer 3

Thank you for your help😉
