NettetOverflow: Integer Arithmetic In the 2's complement number system, nbits can represent the values that must lie within the range -2" “1to +2" ~1- 1. For example, with 4 bits, the range of numbers that can be represented is -8 through +7. NettetIn computer programming, an integer overflow occurs when an arithmetic operation attempts to create a numeric value that is outside of the range that can be represented with a given number of digits – either higher than the maximum or lower than the minimum representable value.. The most common result of an overflow is that the least …
