1.1 Understanding Kotlin's Number Types 📝

Kotlin supports several number types, including:

• Int for whole numbers (like 1, 2, 3)
• Double for floating-point numbers (like 3.14 or 0.0001)
• Long for large whole numbers (like 1000000000)
• Float for floating-point numbers with less precision than Double
• Short and Byte for smaller whole numbers with limited range

💡 Pro Tip: When in doubt, use Double or Int for most scenarios as they offer good precision and range.

1.2 Why Kotlin's Number System Matters 💡

Understanding Kotlin's number system is crucial for writing robust and efficient code. With the ability to handle large and small numbers, as well as floating-point numbers, you'll be equipped to tackle a wide variety of projects.
