Owning Palette: Exponential Functions
Requires: Base Development System
Computes x raised to the y power.
If x is not complex, it must be greater than zero unless y is an integer value. Otherwise, the result is NaN. If y is 0, x^y is 1 for all values of x, including 0. The connector pane displays the default data types for this polymorphic function.

y can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on. |

x can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on. |

x^y is x to the power of y. When x and y are complex, the following equation defines x^y: x^y = exp(y * ln(x)) Refer to the Exponential function and the Natural Logarithm function for more information. |
When you wire matrix data as an input to this function, a VI that includes subVIs that work with the matrix data type replaces the function. The resulting VI has the same icon but contains a matrix-specific algorithm. The node remains a VI if you disconnect the matrix from the input(s). Wire other data types as inputs to restore the original function. If you wire a data type to a function and that data type causes a basic math operation to fail, the function returns an empty matrix or NaN.
Refer to the Matrix Power VI for more information.
Refer to the Exponential VI in the labview\examples\Mathematics\Elementary & Special Functions\Exponential Functions directory for an example of using the Power Of X function.
