How to format a float in javascript?

Question

when converting from a float to a string, how can I get just 2 digits after the decimal point? For example, 5.56 instead of 5.56789.

Answer 1

You can use toFixed() function to get the required number of digits after the “.”. Here is an example of this:

function myFunction() {

  var num = 5.56789;

  var n = num.toFixed(2);

  console.log(n);

}

This would give you an output: 5.56
