You can add a function to Number object and use it anywhere in your page /project.

Add function to Number object

Number.prototype.myPrecision = function(){
    if(Math.round(this)==this){
      return parseInt(this);
    }
    else{
      return this.toFixed(2);
    }
}

How to use 

var n1 = 10.11;
var new_n1 = n1.myPrecision(); // This will output 10.11

//Other case
var n2 = 10.00;
var new_n2 = n2.myPrecision(); // This will output 10

It seems, that the value is stored in string. Cast the value to float, and it should remove the point by itself.

This is the default behavior of JavaScript:

alert(29.100) => "29.1"
alert(28.000) => "28"

document.body.innerHTML = 29.100 => 29.1
document.body.innerHTML = 28.000 => 28

etc.
