Imp Operator


result = expression1 Imp expression2

result: Any numeric variable.

expression1: Any expression.

expression2: Any expression.

The following table illustrates how result is determined:

If expression1 is	And expression2 is	Then 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 bit in expression1 is	And bit in expression2 is	Then result is
0	0	1
0	1	1
1	0	0
1	1	1
