Usage

Example 1

import com.abranhe.bigdecimal.Operations;
import java.math.BigDecimal;

public static void main(String[] args){

        BigDecimal x = new BigDecimal("124567890.0987654321");
        BigDecimal y = new BigDecimal("987654321.123456789");

        System.out.println(Operations.add(x, y));
        //=> 1112222211.2222222211
}

Example 2

import java.math.BigDecimal;

public static void main(String[] args){

        BigDecimal x = new BigDecimal("124567890.0987654321");
        BigDecimal y = new BigDecimal("987654321.123456789");

        Operations o = new Operations();
        System.out.println(com.abranhe.bigdecimal.Operations.divide(x, y));
        //=> 0.12613
}

Example 3

import com.abranhe.bigdecimal.Operations.divide;
import java.math.RoundingMode;
import java.math.BigDecimal;

public static void main(String[] args){

        BigDecimal x = new BigDecimal("124567890.0987654321");
        BigDecimal y = new BigDecimal("987654321.123456789");

        System.out.println(divide(x, y, 9, RoundingMode.FLOOR));
        //=> 0.126124988
}
