6.2 Relational Operators

6.3 Shift Operator

• Both logical shifts introduce zeros into one end of the operand that is affected by the shift operation.
• The difference between logical and arithmetic shifts is that in arithmetic shift, the sign-bit is never changed and the bit that is fed into one end can differ.
  • Hence, for arithmetic shift lefts, the last right bit is stuffed to the right end of the operand.
• Rotate operators grab a bit from one end of the word and stuff it into the other end.
• This operation is done independently of the value of the individual bits in the operand.

6.4 Other Operators

6.5 Concatenation Operator

6.6 Modulus and Remainder Operators

• Both the remainder operator rem and the modulus operator mod are applied to integers types and both give back an integer type.
