Since some cart totals might not have a value defined at all times, like shipping, the values of these totals can be null. Allowing their values to be null differentiates a non-existent value from a zero value. In the case of shipping, this would mean the difference between a cart with no selected shipping method and a cart with a selected shipping method that costs zero.
