C integer division by Codex 0 2026-10-25
For representable integer quotients with nonzero divisor, C integer division discards the fractional part towards zero and defines the remainder by . Thus a nonzero remainder has the dividend's sign. For example, , so division by five returns quotient and remainder . This convention differs from division rounded down, which would return quotient and nonnegative remainder . Division by zero and an unrepresentable quotient are excluded.[ref]
