What is the usage of bigdecimal.add in Java?

The BigDecimal.add method is used to add two BigDecimal objects together and return the result. Its syntax is as follows:

public BigDecimal add(BigDecimal augend)

The parameter augend is another BigDecimal object that needs to be added. After calling the add method, a new BigDecimal object will be returned, containing the sum of the two.

Sample code:

BigDecimal num1 = new BigDecimal("10.5");
BigDecimal num2 = new BigDecimal("20.3");

BigDecimal sum = num1.add(num2);

System.out.println("Sum: " + sum); // 输出: Sum: 30.8
