| When using ''%%Assert.assertEquals()%%'' to compare floating point numbers (e.g., ''%%double%%'' values), one must remember that the ''%%==%%'' operator must be used with care because of the less-than-perfect precision of operations on ''%%double%%'' values. In JUnit, the implication of this is that one should check to see if ''%%double%%'' values are within a tolerance value of each other. Hence, when comparing ''%%double%%'' values one should use the following: | When using ''%%Assert.assertEquals()%%'' to compare floating point numbers (e.g., ''%%double%%'' values), one must remember that the ''%%==%%'' operator must be used with care because of the less-than-perfect precision of operations on ''%%double%%'' values.
