Theory

Welcome to this in-depth video on float and double data types in C++! In this tutorial, we'll break down the key differences between these two floating-point types, how they work behind the scenes, and when to use each one in real-world programming.
👉 What You'll Learn in This Video:
What are float and double data types?
Memory size and precision differences
How to declare and initialise float/double variables
Scientific notation in C++

🧠 Why is this important?
Understanding floating-point types is crucial for writing accurate, reliable C++ programs — especially when dealing with calculations, measurements, or any form of numerical data. Choosing between float and double can impact the precision, performance, and memory usage of your applications.

🔎 Topics Covered:
float (4 bytes) — up to 7 decimal digits of precision
double (8 bytes) — up to 15-16 decimal digits of precision
Real-world scenarios: When to use float vs double
