Unary / Binary
Each operator is either unary or binary in nature. Unary operators are those that operate on
only one operand. For example:
!Flag
^^Total ' square root of Total
Binary operators are those that operate on two operands. For example:
X + Y
Num << 4 ' shift Num left 4 bits
Note that the term “binary operator” means “two operands,” and has nothing to do with
binary digits. To distinguish operators whose function relates to binary digits, we’ll use the
term “bitwise” instead.
Normal / Assignment
Normal operators, like Add ‘
the result for use by the rest of the expression, without affecting the operand or operands
themselves. Those that are assignment operators, however, write their result to either the
variable they operated on (unary), or to the variable to their immediate left (binary), in
addition to providing the result for use by the rest of the expression.
