Question

Hi,

i wonder if there is a function to round a number to a given number of decimals in javascript. For example, to round 2.543686 to 2.54.

The (10.8).toFixed(2); doesn't work in unity, and .ToString(F2); is converting a number to a string.

Thanks.

To be completely honest I don't know for sure. Maybe something like this:

    var randomNumber = 2.543686;

    randomNumber = Mathf.Round(randomNumber * 100.0) / 100.0;

This will round 'randomNumber' to two decimals.

If you want three decimals you can divide by 1000.0.

If you want four decimals you can divide by 10000.0.

And so on.
