Used to perform a logical implication on two expressions.
result = expression1 Imp expression2
The Imp operator syntax has these parts:
Part | Description |
---|---|
result | Any numeric value. |
expression1 | Any expression. |
expression2 | Any expression. |
The following table illustrates how result is determined:
If expression1 is | And expression2 is | The result is |
---|---|---|
True | True | True |
True | False | False |
True | Null | Null |
False | True | True |
False | False | True |
False | Null | True |
Null | True | True |
Null | False | Null |
Null | Null | Null |
The Imp operator performs a bitwise comparison of identically positioned bits in two numeric expressions and sets the corresponding bit in result according to the following table:
If the bit in expression1 is | And the bit in expression2 is | The result is |
---|---|---|
0 | 0 | 1 |
0 | 1 | 1 |
1 | 0 | 0 |
1 | 1 | 1 |
