^= Operator (Visual Basic)
Raises the value of a variable or property to the power of an expression and assigns the result back to the variable or property.
The element on the left side of the ^= operator can be a simple scalar variable, a property, or an element of an array. The variable or property cannot be. The ^= operator assigns the value on its right to the variable or property on its left.
Visual Basic always performs exponentiation in the. Operands of any different type are converted to Double, and the result is always Double.
The value of expression can be fractional, negative, or both.
Thecan be overloaded, which means that a class or structure can redefine its behavior when an operand has the type of that class or structure. Overloading the ^ operator affects the behavior of the ^= operator. If your code uses ^= on a class or structure that overloads ^, be sure you understand its redefined behavior.
