Performs a logical equivalence on two expressions.
result = expression1 Eqv expression2
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|
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|
