I understood your second approach with a union, > but i have some doubts about the first one. What type should 'n' be? It could be __int16, but int_fast16_t is more precisely what I'd want to use. However, I'd normally translate 'int_fast16_t' to 'int', simply because it's easier to type, unless speed is very important.
