Why the heck are you not using BigDecimal in Java?

When it comes to handling precise arithmetic operations with decimal numbers in Java, BigDecimal emerges as the go-to class.

In this article, we'll delve into the world of BigDecimal, exploring its features and comprehensively detailing the operations it supports.

Understanding the Need for BigDecimal

Java’s primitive data types like double and float are excellent for most numerical operations. However, they come with a caveat—limited precision. Floating-point arithmetic can lead to unexpected results, especially when dealing with decimal fractions. Enter BigDecimal, a class in Java that provides arbitrary-precision arithmetic, ensuring accurate representation and manipulation of decimal numbers.

Getting Started with BigDecimal

In this example, we create BigDecimal objects for two decimal numbers and perform basic arithmetic operations—addition, subtraction, multiplication, and division with a specified scale.

import java.math.BigDecimal;

public class BigDecimalExample {
    public static void main(String[] args) {
        BigDecimal num1 = new BigDecimal("10.25");
        BigDecimal num2 = new BigDecimal("5.75");

        // Perform arithmetic operations
        BigDecimal sum =…
