WebReturns whether the bit at position pos is set (i.e., whether it is one). Unlike the access operator (), this function performs a range check on pos before retrieveing the bit value, … WebJul 20, 2009 · Solution 2. It's a matter of using ANDs, and other boolean stuff (if you want to read multiple bits). Basically, you use the formula: bitNSet = (originalInteger & (1 << N) == 1 << N) Effectively, every integer is represented by a binary sequence. For example, 39 would be represented by 100111.

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.

Now, if x is some power of two, then (x – 1) will turn off all the right bits to the set bit (set them as ‘0’) and the set bit would be unset. x = 8 [ 1000 ], x – 1 = 7 [ 0111] forget wifi network windows 11
