Operator + (Addition)

Sums two expressions

Syntax
   Declare Operator + ( ByRef lhs As Integer, ByRef rhs As Integer ) As 
   Integer
   Declare Operator + ( ByRef lhs As UInteger, ByRef rhs As UInteger ) As 
   UInteger

   Declare Operator + ( ByRef lhs As Single, ByRef rhs As Single ) As Single
   Declare Operator + ( ByRef lhs As Double, ByRef rhs As Double ) As Double

   Declare Operator + ( ByRef lhs As T Pointer, ByRef rhs As Integer ) As T 
   Pointer
   Declare Operator + ( ByRef rhs As Integer, ByRef lhs As T Pointer ) As T 
   Pointer

   Declare Operator + ( ByRef lhs As T, ByRef rhs As Integer ) As T
   Declare Operator + ( ByRef lhs As Integer, ByRef rhs As T ) As T

Usage
   result = lhs + rhs

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

Return Value
   Returns the sum of two expressions.

Description
   When the left and right-hand side expressions are numeric values, 
   Operator + (Add) returns the sum of the two values.

   When the left and right-hand side expressions are string values, 
   Operator + (Add) concatenates the two strings and returns the result.

   If an integral value n is added to a T Pointer type, the operator 
   performs pointer arithmetic on the address, returning the memory 
   position of a T value, n indices away (assuming n is within bounds of a 
   contiguous array of T values).  This behaves differently from numeric 
   addition, because the Integer value is scaled by SizeOf( T ).

   Neither operand is modified in any way.

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

Example
   Dim n As Single
   n = 4.75 + 5.25
   Print n

   will produce the output:


   10

Dialect Differences
