Comparing a float and a long appears to convert the long to float and then compare the two floats. This strategy is a problem because the conversion might lose precision. As a result, == is not an equivalence relation and < is not an order relation. For example, it is possible to create three numbers a, b, and c such that a==b, b==c, and a!=c.
