I.4.7.5 Exponent operator

The exponentiation operator can be used as follows:

In the last expression $x$ must be a scalar Result. The tensorial order of the returned Result $z$ is identical to the tensorial order of $x$. The argument $y$ can be either a scalar Result object, or a real value. Complex Results cannot be arguments to this operator. The real values of first Result argument must also be positive.

The three following expressions are equivalent:

            z=x**y
            z=Post.pow(x,y)
            z=Post.opPow(x,y)
