java BigDecimal

java

In Java, the BigDecimal class is a high-precision decimal data type that is used to represent numbers with a large number of digits or with a high degree of precision. It is part of the java.math package and can be used to perform arithmetic operations and compare numbers with a high degree of accuracy.

Here is an example of how to use the BigDecimal class in Java:

import java.math.BigDecimal;

public class Main {
  public static void main(String[] args) {
    // Create a BigDecimal from a string
    BigDecimal x = new BigDecimal("0.1");
    BigDecimal y = new BigDecimal("0.2");

    // Perform arithmetic operations
    BigDecimal sum = x.add(y);
    BigDecimal difference = x.subtract(y);
    BigDecimal product = x.multiply(y);
    BigDecimal quotient = x.divide(y);

    // Print the results
    System.out.println(sum); // prints 0.3
    System.out.println(difference); // prints -0.1
    System.out.println(product); // prints 0.02
    System.out.println(quotient); // prints 0.5
  }
}

This code creates two BigDecimal objects and performs arithmetic operations on them using the add(), subtract(), multiply(), and divide() methods. It then prints the results to the console.
