WebSo, 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. I think this should work properly. Remember to count bits from 0. Share. Cite. Follow. WebDec 4, 2024 · In C++, int is either signed or unsigned and so a bit representation is either signed or unsigned. In a signed representation, first bit represents the sign of a number (0 for positive and 1 for negative), and remaining n-1 bits contains the magnitude of the number. There is a connection between a signed and an unsigned representation.
