code: @Override
      public final boolean matches(JsonNode lhs, JsonNode rhs) {
          return matches(lhs.decimalValue(), rhs.decimalValue());
      }
docs: Converts the lhs and rhs JsonNodes to the numeric values
  and delegates to the matches method that operates on the
  numeric values alone.
  
  @param lhs Lhs expression
  @param rhs Rhs expression
  @return Boolean result of the matches method of the
  corresponding comparison operator
