Protractor - How to Get Value from an Object to Manipulate Value Outside the Promise

Here is the issue I am trying to get value from object inside a promise. I am trying to get the 1st element from a column (Kendo grid). Need to manipulate the value.

Here is the code:

currentAmountDue =  element(((helper.getGridValue(businessPaymentsPage.colAmountDue(), 0)).getText().then(function (value) {
              x = value;
                console.log('x: ', x);
                console.log('Value : ', value);
                return value;
            })));
console.log('x outside : ', x); 

Here are the results:

x outside :  0

x:  $9,750.75

Value :  $9,750.75

I am new to Protractor and Promises.
