Description Of BigDecimal: subtract(BigDecimal subtrahend, MathContext mc)

The java.math.BigDecimal.subtract(BigDecimal subtrahend, MathContext mc) returns a BigDecimal whose value is (this - subtrahend) , with rounding according to the context settings. If subtrahend is zero then this, rounded if necessary, is used as the result. If this is zero then the result is subtrahend.negate(mc) .

BigDecimal.subtract(BigDecimal subtrahend, MathContext mc) method returns this - subtrahend , rounded as necessary.

import java.math.BigDecimal;
import java.math.MathContext;

public class BigDecimalExam {
 public static void main(String[] args) {
  BigDecimal bg1 = new BigDecimal("123.123");
  BigDecimal bg2 = new BigDecimal("12.12");

  MathContext mc = new MathContext(2); // 2 precision
  
  BigDecimal bg3 = bg1.subtract(bg2, mc);

  // print bg3 value
