Eqv Operator

Description

Performs a logical equivalence on two expressions.

Syntax

result = expression1 Eqv expression2

The Eqv operator syntax has these parts:

Part	Description
result	Any numeric variable.
expression1	Any expression.
expression2	Any expression.

Remarks

If either expression is Null, result is also Null. When neither expression is Null, result is determined according to the following table:

If expression1 is	And expression2 is	The result is
True	True	True
True	False	False
False	True	False
False	False	True

The Eqv 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	The result is
0	0	1
0	1	0
1	0	0
1	1	1
