**
Nth power of a first expression, where N is the value of a second expression
Result = expression ** power
For each cell, raises the cell values on expression to the Nth power, where N is the cell value on power. The result of this calculation is assigned to the corresponding cell on Result.
A cell with a value 0 on expression and a value less than or equal to 0 on power is assigned a missing value on Result. Also, a cell with a value less than 0 on expression and a negative whole number on power is assigned a missing value on Result.
A cell with a missing value on expression and/or power is assigned a missing value on Result.
Result **= power is an alternative notation for Result = Result ** power
This operation belongs to the group of Arithmetic operators
