WebSigned overflow occurs when the result of addition is too large for a given type to represent. This occurs when either: Addition of two positive integers result in a negative integer result (so the result msb - the sign bit - is 1 when it should be zero); or. Addition of two negative integers result in a positive integer result (so the result msb is 0 when it should be 1). WebIn 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..
