Operator ^ (Exponentiate)

Raises a numeric expression to some power

result = lhs ^ rhs

The left-hand side base expression.
The right-hand side exponent expression.

Return Value:
Returns the exponentiation of a base expression raised to some exponent.

Operator ^ (Exponentiate) returns the result of a base expression (lhs) raised to some exponent expression (rhs). ^ works with double float numbers only, operands of other types will be converted into double before performing the exponentiation. Exponent of a fractional value (1/n) is the same as taking nth root from the base, for example, 2 ^ (1/3) is the cube root of 2.
Neither of the operands are modified in any way.
Note: this operation is not guaranteed to be fully accurate, and there may be some inaccuracy in the least significant bits of the number. This is particularly noticeable when the result is expected to be an exact number: in these cases, you may find the result is out by a very small amount. For this reason, you should never assume that an exponentiation expression will be exactly equal to the value you expect.

This operator can be overloaded for user-defined types.

Dim As Double n
Input "Please enter a positive number: ", n
Print n;" squared is "; n ^ 2
Print "The fifth root of "; n;" is "; n ^ 0.2

Please enter a positive number: 3.4

 3.4 squared is 11.56
The fifth root of 3.4 is 1.27730844458754
