When I calculate the sum of 4.5 and .525 in HTML, the result is 5.025

When I perform an addition operation in JavaScript, instead of getting the expected result of 4.5 + .525 = 5.025, I receive 4.5.525.

Here is the code snippet:

<!DOCTYPE html>
<html lang="en">
...
            <button class= "btn btn-danger"  style="margin: 2%;
                text-align: center;
                ;
                margin-top: 5%;" onclick="refreshPage()">Reset All</button>
            </div>
<script>
function refreshPage(){
window. location. reload();
}
</script>

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js"
...

    function Calculate() {
        let vl = document.getElementById('VL').value;
        let il = document.getElementById('IL').value;
        let ish = document.getElementById('Ish').value;
        let ra = document.getElementById('Ra').value;
        let ld = document.getElementById('Load').value;
        let vlo = document.getElementById('noLoad').value;

        let SI = (vl * ld)

        ...
        var ef = (SI / OP) * 100
        document.getElementById('Eff').innerHTML = " η % : " + ef;
    }

</script>
<script>
    function myFunction() {
        var element = document.body;
        element.classList.toggle("dark-mode");
    }
</script>

</html>

After setting IL to 4.5 and Ish to .525, the console output incorrectly shows 4.5.525 instead of 5.025.

To address this issue, rewrite and comment the code accordingly for clarity.

In contrast, entering the same values directly into a JavaScript calculation yields the correct answer.

Answer №1

Consider implementing the following approach:

let longitude = (parseFloat(document.getElementById('LT').getAttribute('data-value'));

This code snippet demonstrates how to store the values retrieved from document.getElementById('LT') as a floating-point number in the variable 'longitude'. By converting the value to a float, you can perform arithmetic operations on it without encountering issues with string representations.
