Description
Implements any binary operations of which the custom Variant type is capable.
Override BinaryOp to implement any binary operators the custom Variant type supports.
Left is the value that appears to the left of the operator. BinaryOp changes this value to indicate the result of the operation.
Right is the value that appears to the right of the operator.
Operator identifies the operator that appears between Left and Right. It can be any of the following values:
| Value | Operation |
|---|---|
|
opAdd |
addition |
|
opSubtract |
subtraction |
|
opMultiply |
multiplication |
|
opDivide |
floating-point division |
|
opIntDivide |
integer division |
|
opModulus |
remainder |
|
opShiftLeft |
bitwise left shift |
|
opShiftRight |
bitwise right shift |
|
opAnd |
bitwise and |
|
opOr |
bitwise or |
|
opXor |
bitwise exclusive or |
As implemented in TCustomVariantType, BinaryOp raises a system error indicating an invalid operation.
