WebOct 2, 2024 · A division/multiplication by any number x being a power of 2 can be calculated by shifting log2(x) to the right/left. While the DIV opcode uses 5 gas, the SHR opcode only uses 3 gas. Furthermore, Solidity's division operation also includes a division-by-0 prevention which is bypassed using shifting. WebSAR and SHR shift the bits of the operand downward. The low-order bit is shifted into the carry flag. The effect is to divide the operand by 2. SAR performs a signed divide with rounding toward negative infinity (not the same as IDIV); the high-order bit remains the same. SHR performs an unsigned divide; the high-order bit is set to 0. bucksford law ashford kent
