Operator <> (Not equal)


Compares two expressions for inequality

Syntax:
Usage:
result = lhs <> rhs

Parameters:
lhs
The left-hand side expression to compare to.
rhs
The right-hand side expression to compare to.
T
Any pointer type.

Return Value:
Returns negative one (-1) if expressions are not equal, or zero (0) if equal.

Description:
Operator <> (Not equal) is a binary operator that compares two expressions for inequality and returns the result - a boolean value mainly in the form of an Integer: negative one (-1) for true and zero (0) for false. Only if the left and right-hand side types are both Boolean, the return type is also Boolean. The arguments are not modified in any way.

This operator can be overloaded to accept user-defined types as well.

Examples:

Dim As String a = "hello", b = "world"
Dim As Integer i = 10, j = i

If (a <> b) Then
  Print a & " does not equal " & b
End If

If (i <> j) Then
  Print "error: " & i & " does not equal " & j
End If
Operator = (Equal) is complement to Operator <> (Not equal), and is functionally identical when combined with Operator Not (Bit-wise Complement).

   If (69 <> 420) Then Print "(69 <> 420) is true."
   If Not (69 = 420) Then Print "not (69 = 420) is true."
