how to show two digits after decimal in javascript

Question

I am using JSP for view. I am using angularjs and javascript

I have a text box, in that text box there is a value called 12.542001 . The ng-model should contain the same but when I am showing I want to show 12.54 only on the text box.

If I work with toFixed(2) , Then it will round the value, but I don't want to round that value...

Answer 1

Try this

 console.log(parseFloat(Math.round(12.542001 * 100) / 100).toFixed(2)); //or use num = "122.542001"; var spV= num.split("."); console.log(spV[0] +"."+ spV[1].substring(0,2));

Update

If your ng-model name is $scope.totalnumber . then try this

$scope.totalnumber = parseFloat(Math.round($scope.totalnumber * 100) / 100).toFixed(2)
