Convert Integer to Decimal | Fix Floating-Point Precision Issues
🎯 Python: Convert Integer to Decimal | Fix Floating-Point Precision Issues
In this video, you'll learn how to convert an integer to a decimal using Python's built-in decimal module. We'll also explore the difference between regular float addition and precise decimal arithmetic — a common topic in Python interviews and real-world development!
📌 What you'll learn:
How to convert an int to Decimal
Why 0.1 + 0.2 doesn't equal 0.3 in Python
How decimal.Decimal() helps avoid floating-point precision errors
Importance of using strings when creating Decimal values
🧠 Great for Python beginners, interview prep, and those looking to understand number precision in financial or scientific applications.
🛠️ Code Demo Includes:
import decimal
integer = 20
decimal_value = decimal.Decimal(integer)
print(0.1 + 0.2)
print(decimal.Decimal('0.1') + decimal.Decimal('0.2'))
