Directive Name: aDecimals
How to Use: Add the attribute: n-decimals=”n” where n is the number like 2,3…
If you want to restrict user to 2 decimal points, write like this: evo-decimals=”2″

Source Code:

The following code will restrict user to enter numeric value with decimal upto 4 place.

Javascript code

var app = angular.module('plunker', []);
 
app.controller('MainCtrl', function($scope) {
 
});
 
  app.directive('nDecimals', [nDecimals]);
    function nDecimals() {
        return {
            restrict: 'A',
            link: function (scope, element, attr) {
                element.on('input', function (e) {
                  // Read the attribute to know the 'N' number places
                    var maxDecimal = Number(element.attr('n-Decimals'));
                    //Read the enetered value
                    var sal = element.val();
                    var parts;
                    if (sal.indexOf(".") !== -1) {
                        parts = sal.split(".");
                        if (parts[1].length > maxDecimal) {
                            element.val(sal.substr(0, sal.length - 1));
                        }
                    }
                });
                // destroy event.
                scope.$on('$destroy', function () {
                    element.off('input');
                });
            }
        };
    }

HTML code

 <input type="number" n-decimals="4" ng-model="salary"/>
