Issue #, if available:
Description of changes:
result of short + short is always an int (one of those weird c++ standard quirks), so when we write the result back to a short field some compilers might raise a warning for it if -Wconversion is on (which it is typically not, since its not part of -Wall, etc...). So be more explicit casting back
