The myPow(double, double) method signature implies it calculates with floating point powers while in fact it doesn't. The method signature should read myPow(double, int). Math.pow(double, double) does take floating point powers into account, e.g., Math.pow(4, 0.5) returns the square of 4, so 2, whereas myPow(4, 0.5) would return 4.
