TIL: Quick rounding in JS
In the past I’d always used the Math.round()
function with floor and such to handle rounding to decimal places, turns out there’s a much simpler way of doing it…
To round to say 3 decimal places, just use the toFixed()
method that’s available to any Number
. For example:


The above will return 12.346
, where the method automatically rounds up the value for you.
This is much shorter than the way I’d been doing the math in the past.
