Bitwise operators perform bit manipulations between two expressions of any of the data types of the integer data type category.
Bitwise operators convert two integer values to binary bits, perform the AND, OR, or NOT operation on each bit, producing a result. Then converts the result to an integer.
For example, the integer 170 converts to binary 1010 1010. The integer 75 converts to binary 0100 1011.

AND If bits at any location are both 1, the result is 1. 
1010 1010 = 170 0100 1011 = 75  0000 1010 = 10 
OR If either bit at any location is 1, the result is 1. 
1010 1010 = 170 0100 1011 = 75  1110 1011 = 2795 
NOT Reverses the bit value at every bit location. 
1010 1010 = 170  0101 0101 = 85 
See the following topics:
 & (Bitwise AND)
 &= (Bitwise AND EQUALS)
  (Bitwise OR)
 = (Bitwise OR EQUALS)
 ^ (Bitwise Exclusive OR)
 ^= (Bitwise Exclusive OR EQUALS)

The operands for bitwise operators can be any one of the data types of the integer or binary string data type categories (except for the image data type), except that both operands cannot be any one of the data types of the binary string data type category. The following table shows the supported operand data types.
