Web3 Answers Sorted by: 5 I got an idea, at least I would do it like this. So, bit_value = ( (uint8_variable>>BIT_NEEDED)&1) So this would shift the bit you need in LSB position, and the & operator would mask the other bits. Example: uint8_variable = 0110 1010 BIT_NEEDED=3 0110 1010 >> 3 = 0000 1101 0000 1101 & 0000 0001 = 0000 0001 Web27 de may. de 2024 · 2. Left shift the ones mask to the starting position from where we have to copy the bits. The ones mask will now have 1’s from the start bit position to the end bit position. In this example, starting bit position is 4, so we perform (ones_mask 4) = (0xF 4) = 0xF0. 3. Construct a zeroes mask which is the complement of the ones mask. megan ashley instagram
