Web3 aug. 2024 · I have this confusion regarding binary representation of decimal value 129 (or even 128). If 8 bits are used to represent numbers when doing the two's complement, then we know that '00000000' to '01111111' are used for 0 to 127 and leading 1 is used for negative numbers i.e. 1xxxxxxx where x is any combination of 0's and 1's to represent … WebTwo's compliment representation of signed integers is easy to manipulate in hardware. For example, negation (i.e. x = -x) can be performed simply by flipping all the bits in the … dave and busters bowling prices houston
