The multiplication sum is not being calculated correctly after the decimal point in JavaScript

Just dipping my toes into the world of JavaScript, so please be gentle!

I'm currently working on a function that multiplies one input field by another that the user provides. However, there seems to be an issue when the user wants to multiply by 8.5 - it only takes the integer value, not the decimal.

How can I ensure that the full number, including the decimal, is multiplied correctly?

Here's what my function looks like so far:

function calculate() {
    amount = parseInt(document.getElementById("amount").value);
    prev = parseInt(document.getElementById("previous").value);
    result = amount * prev;
    document.getElementById("return").value = result; 
}

I've been searching for a solution online, but I'm struggling to find the right answer. Any help would be greatly appreciated!

Answer №1

Switch from parseInt to parseFloat

function calculate() {
    inputAmount = parseFloat(document.getElementById("amount").value);
    previousVal = parseFloat(document.getElementById("previous").value);
    result = inputAmount * previousVal;
    document.getElementById("result").value = result;
}
