Number System
How do I calculate (-54)10 in hexadecimal? The way I am doing it currently is that I am first converting (54)10 into hexadecimal which is (34)16. Next I am taking 16's complement. i.e. I am doing (FF)16 - (34)16 + 1, which comes to (CA)16. Thus, (-54)10 = (CA)16. Is this the right way to convert or is there some better method ?
