Thepowerfunction evaluates abaseby raising it to the power of a givenexponent.
Examples
Thepowerfunction can be used to raise a number to the power of another number. For example, 23would be written as:
power(2, 3)
Typically, thepowerfunction is used with a field reference or an expression.
For example:
power(${order_item.standard_deviation_profit},2)
Things to know
Thepowerfunction can also be used to take the nth root of a number by using 1/n as theexponent. For example, the cube root (the 3rd root) of 7 would be:
power(7, 1/3)
For a square root (the 2nd root) just use thesqrtfunction.
