Update FedexService.cs

The existing behaviour leads to XSD scheme validation errors. The dimensions suppose to be passed as Integer values.

@borissedov this calculation is technically incorrect. FedEx wants you to round fractions to the nearest whole inch.
So 4.4 becomes 4 and 4.5 becomes 5.
Your change may result in undersized calculation.

I understand that it may cause rounding issue but the Fedex API doesn’t accept float values for this field. I have found it in our project and want to share the experience.

Yes I understand. I would suggest that you do actual rounding using Math.Round() instead of simply casting to an integer. This will make the value correct.
