Modify your pow method from Exercise 5 to make a new method called pow2 that uses the type double for the first parameter and that works correctly for negative numbers. For example, the call pow2(–4.0, 3) should return –4.0 * –4.0 * –4.0 , or –64.0 , and the call pow2(4.0, –2) should return 1 / 16, or 0.0625.

Data from Exercise 5

Write a method called pow that accepts a base and an exponent as parameters and returns the base raised to the given power. For example, the call pow(3, 4) should return 3 * 3 * 3 * 3, or 81. Assume that the base and exponent are nonnegative.
