Problem resolved: Assign the nearest *multiple of ten* to a number if it surpasses the last *multiple of ten*

Consider this scenario:
You have a number, let's say 12.5, and you want to round it up to the next multiple of ten (20). Or if you have a number between 20 and 30, it should be rounded up to 30.
How can this be achieved using JavaScript?
I have searched extensively for a solution but haven't found one yet.

UPDATE: I made a small English mistake in my explanation earlier. What I meant was the nearest multiple of ten (10, 20, 30).

UPDATE 2: Following the method provided in the answer below (now marked as correct), I was able to successfully address my issue.

javascript

Answer №1

When considering the concept of rounding up to the nearest ten, it's essential to clarify whether you mean the closest dozen or just the next consecutive ten. To achieve this calculation, utilize the following function:

function roundUpToTen(number) {
    return Math.ceil(number / 10) * 10;
}

console.log(roundUpToTen(17.3)); // Output: 20
console.log(roundUpToTen(28));   // Output: 30
