The tests cases used an exact test for equality. In terms of floating point numbers, this is incorrect as a test, because it can fail to recognize entirely valid solutions, and there are many ways to validly solve this problem. As such, I modified the test cases to use a tolerance on the result.

It's the floating-point precision that matters.
