Description: BigDecimal is a class in Ruby (and other programming languages) designed to represent immutable decimal numbers of arbitrary precision. This class is particularly useful in applications that require financial or scientific calculations where precision is crucial. Unlike standard numeric data types, which can suffer from rounding and precision issues due to the binary representation of numbers, BigDecimal allows developers to work with decimal numbers more accurately and in a controlled manner. The immutability of BigDecimal objects means that any operation that modifies the value of a BigDecimal will generate a new object instead of altering the original, helping to avoid errors in complex calculations. Additionally, BigDecimal provides a variety of methods for performing arithmetic operations, comparisons, and conversions, making it a versatile tool for handling decimal numbers in programming. Its use is fundamental in contexts where decimal precision is essential, such as financial calculations, statistics, and any other area that requires rigorous handling of decimal numbers.
