## UseCaretForExponent

​

The UseCaretForExponent option lets you get or set if the caret character `^` should behave as an exponent operator instead of an XOR (logical exclusive OR) operator. For example, you want the following expression, `2^3` to return 8 (2 to the power of 3). The double caret `^^` (`2^^3`) already acts as an exponent operator whether this option is enabled or not. By default, the UseCaretForExponent value is `false`.

​

In this example, we will use the math expression 2 power 3 by first using a double caret and then by setting our `UseCaretForExponent = true` option and using a single caret. In both cases, the result will be 8.

​

> NOTE: A new operator '^|' is available for the bitwise exclusive-OR operator.
