I am trying to format a decimal value so that it is always sent in this format: 00.00, I have an example in this site link

If you enter 20.10 = 20.1 (you want it to look like 20.10) if you enter 15.00 = 15 (you want it to stay 15.00)

   <input class="form-control input-sm"  type="number" name="myDecimal" placeholder="Decimal" ng-model="numero.valor" ng-pattern="/^[0-9]+(\.[0-9]{1,2})?$/" step="0.01" />

ng-pattern is only used for validation, in addition you will need to create a policy that requires ngModel and include a $ parse to do this work.

In summary do something like:

angular.module('seuApp').directive('suaDirective', function() {
  return {
require: 'ngModel',
link: function(scope, element, attrs, ngModelController) {
  ngModelController.$parsers.push(function(data) {
    return parseFloat(data).toFixed(2); //converted
  });
}
  }
});

Then just include it in HTML.
