public class BigDecRelational
extends Comparative

Implements the relational operations <, >, <=, >=, != and ==. BigDecimals can be compared to each other. Boolean values can be compared to each other. If the allowStrings option is set then Strings can be compared to each other. An illegal parameter exception is thrown if BigDecimals and Booleans or BigDecimals and Strings or Booleans and Strings are compared.

Version:

5.3 Now extends Comparative so can be used in MinMax
