I was wondering if it is possible to get the approximate number in Javascript? Like if I had a large number for example

var number = 537989;

A bit like the Math.round() , just so it rounds up to 538000. Is there a way to do so? Thanks.

• javascript
• integer
• rounding

• 2 Did you try dividing by 10,000, then applying round()? – Frédéric Hamidi Commented Jan 4, 2014 at 20:43

You can write it yourself. Something like

function myround(number, precision = 1000) {
    var result = Math.round(number / precision) *  precision;
    return result;
}

I wrote a JS library, approximate-number, that does this and a bit more. For example, 537989 would get approximated to "537k" by default or "538k" if you set round: true.
