# **¶

**

Nth power of a first expression, where N is the value of a second expression

Result = expression ** power

expression
spatial, non spatial scalar
power
spatial, non spatial scalar
Result
spatial if expression or power is spatial, else non spatial scalar

## Operation¶

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.

## Notes¶

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

## Group¶

This operation belongs to the group of Arithmetic operators

## Examples¶

1. • pcrcalc
binding
Result = Result.map;
Expr = Expr.map;
Power = Power.map;
initial
report Result = Expr ** Power;
