Pow - method of the Pm object

Description:
Computes the value of "x raised to the power of y".
Syntax:
Double Pow(Double nX, Double nY)
Parameters:
nX(Double) Base number
nY(Double) Requested exponent
Note:
This method is functional also in Macro expression $.expr and in the onDraw event of the PmgCanvas object.
This method is also functional in Web panels.

If the computation results in a complex number, then the method returns NaN. This means that in reality the nX should not be a negative number.
The high value of the nY exponent may easily lead to floating point overflow returning the Infinity value.
Example:

var a = 3;
var b = Pm.Pow( a, 2);  //Returns 9
b = Pm.Pow( a, 1 / 3);  //Returns "third root of three"
