Due to how JS implements numbers, it's possible that when we multiple a number with 2 decimal places by 100 that we do not end up with an integer e.g. 9.95 * 100 = 994.999...
This is not a valid price for the API and so we must round it to the nearest integer. We round off prices both at source as well as in ties serializer to make sure we never send non integer prices to API.
