Floating Point & BCD Codes Explained | Computer Fundamentals Made Easy

Floating Point Representation and BCD (Binary Coded Decimal) Codes are two important concepts in Computer Fundamentals, Digital Logic, and Computer Architecture. These concepts help computers represent real numbers, decimal values, and perform accurate calculations in various digital systems. In this video, we explain Floating Point Representation and BCD Codes in a simple, beginner-friendly, and exam-oriented manner.

You will learn how computers store very large and very small real numbers using floating point representation and how decimal digits are encoded into binary using BCD and 8421 codes. We will also explore the structure of floating point numbers, including the Sign Bit, Exponent, and Mantissa, along with practical examples and real-world applications.
