Why the downvotes? It answer the question. As I'm not a deep coder, what are the advantages of having an integer type versus a float type in the case of Javascript? Memory? Not having to use Math.floor, Math.ceil, or Math.round in case of funky divisions? I've used Javascript for years now without worrying over that particular detail.
