WebFeb 23, 2024 · Arithmetic rules. ES.100: Don’t mix signed and unsigned arithmetic; ES.101: Use unsigned types for bit manipulation; ES.102: Use signed types for arithmetic; ES.103: Don’t overflow; ES.104: Don’t underflow; ES.105: Don’t divide by zero; ES.106: Don’t try to avoid negative values by using unsigned 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.
