I have tried different values : 0xFF-1 give the same bad result 100 give correct result without casting WebBitwise left and right shift operators << >> The bitwise shift operators move the bit values of a binary object. The left operand specifies the value to be shifted. The right operand specifies the number of positions that the bits in the value are to be shifted. The result is not an lvalue.

WebTo check a bit, shift the number n to the right, then bitwise AND it: bit = (number >> n) & 1U; That will put the value of the n th bit of number into the variable bit. Changing the n th bit to x Setting the n th bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n);
