The Function Exponent Power command in the expression editor inserts the token pow(<x>,<y>) at the insertion point in the editing pane. This token evaluates the value x^y where x and y are other expressions. Replace
the dummy arguments as follows:
<x>
Replace with an expression for the base, that is, the expression to be raised to the power of the second expression.
<>
Replace with an expression for the exponent.
Example
pow(sphere.polymsh.geom.sphere.radius, 1/3)
Returns the cubic root of the radius of a polygon mesh sphere.
