lz_root_n
The root of the left number whose order is the right.
long lz_root_n( CLZNumber* leftOperand, CLZNumber* rightOperand, CLZNumber* targetNumber = nullptr );x1/n. Where one over the order is whole it is a power, so the root of order ½ is the square; otherwise it is e to the logarithm over the order. An odd whole order takes a negative number to its real root: the fifth root of −32 is −2. A root of whole order exactly on a half is decided exactly.
