I'm using an exif reader to extract geo data from a photograph:data.latitude = Number(exif.getTagDescription('GPSLatitude'));I would like the answer to 6 decimal places, so that the output in the console reads 52.629147 instead of 52.62914722222222. Please tell me how to do this?

My question is different to Round to at most 2 decimal places in JavaScript because as a newby this question is not in the context of extracting integers - represented as values - from external media; rather it is just simple numbers.

Use toFixed(n)

(10/3)

  • 3.3333333333333335

(10/3).toFixed(4)

  • "3.3333"

This gets you a string, so you may need to convert it back.

Number((10/3).toFixed(4))

  • 3.3333

I have created the function below for you. 

function roundMyNumber(n) {
    return n.toString().indexOf(".") != -1 ? n.toFixed(6) : n;
}

Take a look this Demo: http://jsfiddle.net/9a7oxgek/1/

I hope it's helps.
