public S usingComparator(Comparator<? super Float> customComparator)

```
 // frodo and sam are instances of Character with Hobbit race (obviously :).
 // raceComparator implements Comparator<Character> 
 assertThat(frodo).usingComparator(raceComparator).isEqualTo(sam);

    This method should be used to disable a custom comparison strategy set by calling Assert.usingComparator(Comparator).
    
    Specified by:
    
    usingDefaultComparator in interface Assert<S extends AbstractFloatAssert<S>,Float>
