Shift operator
Including: ">> right movement"; "<< left shift"; ">> No symbol right shift "
Example: -5 >> 3 = -1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 The result is identical to Math.Floor (Double) -5 / (2 * 2 * 2)).
-5 << 3 = -401111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1101 1000 The result is identical to -5 * 2 * 2 * 2.
5 >> 3 = 0000 0000 00 00 00 00 00 00 00 00 00 00 00 00 0000 The result is exactly the same as 5 / (2 * 2 * 2).

Regardless of the positive number, negative, their right shift, left shift, no symbol right shift 32 bits itself, such as -5 << 32 = -5, -5 >> 32 = -5, -5 >>> 32 = -5. One interesting phenomenon is to move 1 left to 31 points and then remove 31. The result is -1.0000 0000 0000 0000 0000 0000 00 00 00 00000000 0000 0000 0000 0000001111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111
Bit logical operator
Includes: &; | or; ~ non-(also known as a reverse); ^
"&", "| Or", "~ Non" is a basic logic, thereby evolving "with non-", "or non-", "or non-" composite logic operations. "^ Di or" is a special logical operation, which can be "same or" on it, so "the same or" logic is also called "different or non-" logic.
Examples: 5 = 1000000000000 & 3 0000 0000 0000 0000 0,101,000,000,000,000 0000 0000 0000 0000 0,011,000,000,000,000 0000 0000 0000 0000 0001
