![]() ![]() Notice how two rightmost bits, 01, have been shifted off, and two zeroes have been shifted in from the left. In both cases, the sign of the binary number is given by its leftmost bit: for the positive decimal number 9, the leftmost bit of the binary representation is 0, and for the negative decimal number -9, the leftmost bit of the binary representation is 1. Notice that the binary representation of the negative decimal (base 10) number -9 is the two's complement of the binary representation of the positive decimal (base 10) number 9. The other bitwise operators, zero-fill right shift returns an unsigned 32-bit integer.Ĭonsider the 32-bit binary representations of the decimal (base 10) numbers 9 and -9: 9 (base 10): 00000000000000000000000000001001 (base 2) The sign bit becomes 0, so the result is always non-negative. This operator shifts the first operand the specified number of bits to the right.Įxcess bits shifted off to the right are discarded.
