Eqv Operator

Performs a logical equivalence on two expressions.

result = expression1 Eqv expression2

result

Any numeric variable.

expression1

Any expression.

expression2

Any expression.

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

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
