Please supply more than one test case and check each and every problem before posting. The current test suite has the wrong answer for the only case and can, therefore, not be properly solved.

This problem has been fixed and is now solvable.

Applied a tolerance, which is crucial, since tiny variations in the least significant bits due to floating point arithmetic can cause a valid solution to fail.
