java.math.BigDecimal.xor(BigInteger val)

Description Of BigDecimal: compareTo(BigDecimal val)

The java.math.BigDecimal.xor(BigInteger val) compares this BigDecimal with the specified BigDecimal . Two BigDecimal objects that are equal in value but have a different scale (like 2.0 and 2.00) are considered equal by this method. This method is provided in preference to individual methods for each of the six boolean comparison operators (<, ==, >, >=, !=, <=). The suggested idiom for performing these comparisons is: (x.compareTo(y) < op > 0) , where < op > is one of the six comparison operators.

BigDecimal.compareTo(BigDecimal val) method returns -1, 0, or 1 as this BigDecimal is numerically less than, equal to, or greater than val

Code Example Java BigDecimal

import java.math.BigDecimal;

public class BigDecimalExam {

  }
 }
