WebSigned and unsigned division are different operations, owing to the need to round towards zero. For example, in unsigned 4-bit integer arithmetic, 1001/0010 yields 0100 (9/2 = 4), while in signed 4-bit integer arithmetic it yields 1101 (–7/2 = –3). We follow LLVM in calling signed and unsigned division sdiv and udiv, respectively.
