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
