Overflow in binary addition occurs when the result of adding two binary numbers exceeds the range that can be represented with the given number of bits. This is particularly relevant in computer systems that use fixed-size registers to store numbers.
Conditions for Overflow
Overflow can occur under the following conditions:
Addition of Two Positive Numbers: When adding two positive numbers, if the result exceeds the maximum value that can be represented, overflow occurs. For example, in a 4-bit system, adding 7 (0111) and 1 (0001) results in 8 (1000), which cannot be represented in 4 bits1.
Addition of Two Negative Numbers: When adding two negative numbers, if the result is less than the minimum value that can be represented, overflow occurs. For example, in a 4-bit system, adding -8 (1000) and -1 (1111) results in -9, which cannot be represented in 4 bits2.
Carry-In and Carry-Out Bits: Overflow can also be detected by comparing the carry-in and carry-out bits of the most significant bit (MSB). If these two bits are different, overflow has occurred. For example, if the carry-in is 1 and the carry-out is 0, or vice versa, overflow is detected1.
Overflow in Arithmetic Addition in Binary Number System
The binary number system is a base-2 numeral system that uses two symbols: Zero and one respectively.
