.toFixed not for .0*

Question

I have a few values:

var one = 1.0000
var two = 1.1000
var three = 1.1200
var four = 1.1230

and function:

function tofixed(         


        

Answer 1

The "correct" way to do it is as follows:

return Math.round(num*100)/100;

If you want to truncate it to two decimal places (ie. 1.238 goes to 1.23 instead of 1.24), use floor instead of round.
