Python Decimal Module: Techniques for Enhanced Numeric Accuracy

In Python3, the decimal module provides support for fast correctly-rounded decimal floating-point arithmetic. It offers several advantages over the built-in binary floating-point representation, such as more accurate handling of decimal fractions, customizable precision, and controlled rounding modes. This module is particularly useful for financial applications where exact decimal representation is required. By using the decimal context, users can manage precision and rounding to suit specific computational needs.

This Python code demonstrates the use of the decimal module for precise arithmetic operations. It includes setting precision, performing basic calculations, and adjusting the precision and rounding. The example highlights Decimal's ability to handle more accurate calculations than standard floating-point arithmetic.
