: 128 bits (maximum representable value approx. 10³⁸)

Since an arithmetic operation may produce a result larger than the maximum representable value, a potential error condition may result. In the [[C (programming language)|C programming language]], for example, signed integer overflow causes [[undefined behavior]], althoughwhile arithmeticunsigned oninteger unsignedoverflow integers,causes however,the number to isbe reduced [[modular arithmetic|modulo a power of two]], meaning that unsigned integers "wrap around" on overflow.
