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
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.

Examples:
Dim n As Single
n = 4.75 + 5.25
Print n
n = 4.75 + 5.25
Print n
will produce the output:
10
Dialect Differences:
- In the -lang qb dialect, this operator cannot be overloaded.
Differences from QB:
