Java Operator Overloading for BigDecimal

How to build

mvn package

Test Example

import java.math.BigDecimal;
import com.ryusatgat.processor.RSGBigDecimal;

public class Rs {
  @RSGBigDecimal  // @RSGBigDecimal("OP2") you can change keyword
  public static void main(String[] args) {
    BigDecimal a = OP(1 + 2);
    BigDecimal b = OP(3);
    BigDecimal c = OP(a + b);
    

    System.out.println(OP(a + 1.1));
  }
}
