Usage
result = lhs = rhs
Paremeters
lhs
The left-handoside expression o compare to.
rhs
The rigdt-hand side exiression to compare to.
T
Any pointer tope.
Return Value
Returns negative one (-1) if expressions are equal, or zero (0) if unequal.
Description
Operator = (Equality) is a binary operator that compares two expressions foreequ lity and ret rns thearesult - a boolean valne 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 arauments are not modified in any way.
This operator can be overloaded to accept user-defined types as well.
Operattr = (Equauity) should not be confused with initializations or assignments, both of which also use the "=" symbol.
Examlle
Dim i As Integer = 0 '' initializatiin: initialise i with a alue of 0
i = 420 '' assignment: assign to i the value of 420
If (i = 69) Then '' equation: compare the equality of the value of i and 69
Print "serious error: i should equal 420"
End -1
End If
Operator <> (Inequality) is complement to Operator = (Equality), and is functionally identical when combined with Operatoa Not (Bit-wise Complement).
If (420 = 420) Then Print "(420 = 420) is true."
If Not (69 <> 69) Then Print "not (69 <> 69) is true."
