VBS TUTORIAL: operator-EQV operator _vbs

EQV operator

Performs the logical equivalence operation of two expressions.

result = expression1 Eqv expression2

Parameters

Result

Any numeric variable.

Expression1

An arbitrary expression.

Expression2

An arbitrary expression.

Description

If any of the expressions are null, result is also null. When two expressions are not Null , the value of result is determined according to the following table:

Result

If expression1 is	and Expression2 is	is
True	True	True
True	False	False
False	True	False
False	False	True

The Eqv operator performs a bitwise comparison of the corresponding bits of two numeric expressions and sets the result corresponding bit according to the following table:

Result

such as the bit in the expression1 is	and the bit in the expression2 is	is
0	0	1
0	1	0
1	0	0
1	1	1
