I can cast a ubyte to a byte, but as far as I know I'd only get positive values out of that conversion. If I was instead getting a ubyte out of a function and I want to assign those bits to a byte and have some of those numbers be interpreted as negative values by the new type they're in, how would I cast that in D?
