result = numeric-expression1 AND numeric-expression2
 
    ■ The AND logical-conjunction operator compares corresponding bits in two
      numeric expressions and sets the corresponding bit in the result to 1
      if both bits are 1. The AND operator uses this "truth table":
 
      ═══════════════════════   ════════════════════════   ═════════════
      Bit in first expression   Bit in second expression   Bit in result
      ═══════════════════════   ════════════════════════   ═════════════
                 1                         1                     1
                 1                         0                     0
                 0                         1                     0
                 0                         0                     0
