/**
 * This Function overrides the default Bid Field comparison of using {@code equals()} with {@code compare()}.
 * It is needed because BigDecimals' {@code equals()} takes into account the number's scale, which means 

 * {@code 0.0 != 0.00} 

 * This can cause strange behaviours, especially when comparing UI values against DB values.

 * Using {@code compare()} instead solves this problem as it ignores scale when the values are the same.
