operator

- Return type:
- Integer
- Returns:
- A bit sequence.

complement numeric-expression

The complement of two bit sequences is a new sequence where each bit is "flipped". In other words, each bit is:

- 1 if the corresponding operand is 0
- 0 if the corresponding operand is 1

For example, the complement of 0 is "111111111111111111111111111111111111" base 2. (This actually results in a negative number on most systems because the topmost bit is a sign bit. A "1" in this position usually indicates a negative number. This is one reason to avoid dealing with numeric expressions as both bit sequences and numbers at the same time.)

Other languages sometimes refer to this operator as a "bit-wise not" because the operation is analogous to the logical "not" operation. To avoid confusion, OmniMark reserves the operator "!" (`not`

) for the logical "not" operation.

Usage example:

set c to complement 1 set c to c mask complement 1
