WebApr 8, 2016 · Bits aren't given numeric positions. Instead we speak of the least significant bit (LSB) and the most significant bit. Unfortunately, in general things aren't that simple. The generalization of the LSB is the "lower 8 bits" or the "lower 4 bits", and you might speak of e.g. the 3rd-lowest bit. Insofar, terminology is definitely 1-based.

Weba function that determines the bit-index of the least significant 1 bit ( LS1B) or the most significant 1 bit ( MS1B) in an integer such as bitboards. If exactly one bit is set in an unsigned integer, representing a numerical value of a power of two, this is equivalent to a base-2 logarithm. WebSuppose we wish to find the lowest set bit of x (which is known to be non-zero). If we subtract 1 from x then this bit is cleared, but all the other one bits in x remain set. I don't understand how this statement is true. If we take x = 110, subtracting 1 would give 101. Here, the lowest set bit is not cleared. portable dishwasher winnipeg

I don't understand how this statement is true. If we take x = 110, subtracting 1 would give 101. Here, the lowest set bit is not cleared. WebIf we add 1 from the number, it will make the most unset bit to 1, if there are any set bits on the right side of the unset bit, that bit will become zero. (example : 1 0 1 1 + 0 0 0 1 = 1 1 0 0) So if we negate the original number it will make the rightmost unset bit to 1.
