BigDecimal equals() versus compareTo()
... Unlike compareTo, this method considers two BigDecimal objects equal only if they are equal in value and scale (thus 2.0 is not equal to 2.00 when compared by this method).
In other words: equals() checks if the BigDecimal objects are exactly the same in every aspect. compareTo() "only" compares ...
