Power Function
Math Complex Class

Public Function Power( _
      ByVal vX As Variant _
    , ByVal vY As Variant _
    ) As Variant

"X To The Power Of Y"
X and Y can be real and/or complex numbers.

Examples: 
    ? Power(-2, 3)
    -7.99999999999995|7.39933288251833E-14
    ? Power("-3|-4", 3)
    117|-43.9999999999996
    ? Power(3, "-3|-4")
    -1.15781594088179E-02|3.51807950050429E-02
    ? Power("-5|-7", "-3|-4")
    -1.09877143234855E-07|-2.19453107393805E-07

vX: The number which is raised to the power vY. Function returns Null if vX is Null or cannot be fixed up to a real or complex number (as defined by the ComplexStringToReals function). Complex numbers are represented within strings as "R|I" where R is the real part and I is the imaginary part.

vY: The power to which vX is raised. Function returns Null if vY is Null or cannot be fixed up to a real or complex number.

Note: Power(X, 2) is equivalent to but less accurate than Square(X).
Definition: 

    Exponent(Logarithm(X) * Y)
