Checking if a value has more than 3 decimal places in AngularJS-CodePudding

As the title states I am trying to check if a value had greater than 3 decimal places. This is the first time that I have had to deal with angularjs and I am not certain how to check that. I have check if value is whole number, greater than 0, etc.. But I am uncertain on the decimal places. Here is a snippet of my whole number check. Any suggestions on how I could do the check for the decimals would be greatly appreciated. I am trying to show a error message if the user goes over 3 decimals places.

Whole number example:

(mySubmittedOrder && myQuantity % 1 ===0)

CodePudding user response：

var num1 = 1.123;

  function decimalCount(num){
    var numStr = String(num);
    // String Contains Decimal
    if (numStr.includes('.')) {
      return numStr.split('.')[1].length;
    };
    // String Does Not Contain Decimal
    return 0;
  }

  var decimalNumber = decimalCount(num1);

  if(decimalNumber == 3){
    console.log("3 decimals");
  }else{
    console.log("Not 3 decimals");
  }

jQuery :

$filter('number')(number, fractionSize)

or Angular:

<span id='number-default'>{{val | number}}</span><br>
