Javascript: Round up to the next multiple of 5

I need a utility function that takes in an integer value (ranging from 2 to 5 digits in length) that rounds up to the next multiple of 5 instead of the nearest multiple of 5. Here is what I got:

function round5(x)
{
    return (x % 5) >= 2.5 ? parseInt(x / 5) * 5 + 5 : parseInt(x / 5) * 5;
}

When I run round5(32), it gives me 30, where I want 35.
When I run round5(37), it gives me 35, where I want 40.

When I run round5(132), it gives me 130, where I want 135.
When I run round5(137), it gives me 135, where I want 140.

etc...

How do I do this?

This will do the work:

function round5(x)
{
    return Math.ceil(x/5)*5;
}

It's just a variation of the common rounding number to nearest multiple of x function Math.round(number/x)*x, but using .ceil instead of .round makes it always round up instead of down/up according to mathematical rules.

const roundToNearest5 = x => Math.round(x/5)*5

This will round the number to the nearest 5. To always round up to the nearest 5, use Math.ceil. Likewise, to always round down, use Math.floor instead of Math.round. You can then call this function like you would any other. For example,

roundToNearest5(21)

will return:
