+ Operator Example
This example uses the
+ operator to sum numbers. The
+ operator can also be used to concatenate strings. However, to eliminate ambiguity, you should use the
& operator instead. If the components of an expression created with the
+ operator include both strings and numerics, the arithmetic result is assigned. If the components are exclusively strings, the strings are concatenated.
Dim MyNumber, Var1, Var2
MyNumber = 2 +
2 ' Returns 4.
MyNumber = 4257.04 +
98112 ' Returns 102369.04.
Var1 = "34": Var2 = 6 ' Initialize mixed variables.
MyNumber = Var1 +
Var2 ' Returns 40.
Var1 = "34": Var2 = "6" ' Initialize variables with strings.
MyNumber = Var1 +
Var2 ' Returns "346" (string concatenation).
