java.math.BigDecimal.byteValueExact()

Description Of BigDecimal: byteValueExact()

The java.math.BigDecimal.byteValueExact() converts this BigDecimal to a byte , checking for lost information. If this BigDecimal has a nonzero fractional part or is out of the possible range for a byte result then an ArithmeticException is thrown

BigDecimal.xor(BigInteger val) method returns this BigDecimal converted to a byte

Code Example Java BigDecimal

import java.math.BigDecimal;

public class BigDecimalExam {
 public static void main(String[] args) {
  // assign values to bg1 and bg2
  BigDecimal bg1 = new BigDecimal("-4");
  BigDecimal bg2 = new BigDecimal("2");

  byte i1 = bg1.byteValueExact();
  byte i2 = bg2.byteValueExact();

  // print i1,i2 values
  System.out.println(i1);
  System.out.println(i2);
 }
}
