2's Complement Arithmetic

I this video, how to perform the addition and subtraction of signed binary numbers using is explained using examples.
The advantage of 2's complement arithmetic is that the subtraction can be performed in a very similar way to the addition of two numbers.

Condition of Overflow:

While performing the addition or subtraction using 2's complement arithmetic, one should be careful about the range.
If the addition or subtraction is out of the n- bit 2's complement representation range then the result after addition or subtraction will be invalid and it is the case of overflow.
In this video, the condition of overflow is explained with the help of few examples.

$Floating Point Numbers: IEEE 754 Standard | Single Precision and Double Precision Format In this video, IEEE 754 standard, and specifically IEEE single precision and double precision format for the floating point numbers is explained in detail. And through examples, how to convert the 32-bit floating point numbers into the equivalent decimal number and vice-versa, how to convert the decimal number into a 32-bit floating point number is explained. At the end, why the floating point numbers cover a greater range compared to fixed point numbers (with the same bits) is also explained. Here is the list of topics covered in the video: 0:00 Introduction 2:13 Single Precision Format 7:14 Example 1 9:14 Example 2 11:31 Example 3 15:16 Why does a Floating Point Number cover a greater range than a Fixed Point Number? 19:33 Double Precision Format For more videos on Digital Electronics, check this playlist: https://youtube.com/playlist?list=PLwjK_iyK4LLBC_so3odA64E2MLgIRKafl&si=j61PCIBIu7_sCHuU IEEE 754 Standard: In IEEE 754 standard, depending on how many bits are reserved for storing the floating point numbers, there are different formats. 1) Half-Precision Format (16-bits) 2) Single Precision Format (32 bits) 3) Double Precision Format (64 bits) 4) Quadruple Precision (128 bits) 5) Octuple Precision (256 bits) Among all, Single Precision and Double Precision Formats are widely used. And in this video these two formats are explained in detail. Single Precision Format (32 bit Floating Point Numbers): In this format, out of the 32 bits, 1) 1 bit is reserved for sign. 2) 8 bits are reserved for exponent 3) 23 bits are reserved for mantissa / significand To represent any binary number in this format, first binary number is normalized and then it is stored in this 32-bit format. For Mantissa, the digit before the binary point (which is always 1) is not stored explicitly and only fractional part is stored. The exponent is stored in biased format. For 32-bit numbers, the bias value is 127. In the actual exponent value, this bias (127) is added and then the exponent is stored. Because of this offset, all the negative numbers will get shifted towards the positive side. In this 32-bit format, the actual value of the exponent can range from -126 to +127. Double Precision Format (64-bits Floating Point Numbers) To achieve more precision and even more range, Double Precision Format is used. In this format out of the 64-bits, 1) 1 bit is reserved for sign. 2) 11 bits are reserved for exponent 3) 52 bits are reserved for mantissa / significand For 64-bit numbers, the bias value is 1023. In the actual exponent value, this bias (1023) is added and then the exponent is stored. Because of this offset, all the negative numbers will get shifted towards the positive side. In this 64-bit format, the actual value of the exponent can range from -1022 to +1023. This video will be helpful to all the students of science and engineering in understanding the IEEE 754 standard for the Floating Point Numbers. #ALLABOUTELECTRONICS #digitalelectronics #floatingpointnumbers #IEEE754 Support the channel through membership program: https://www.youtube.com/channel/UCBkOVp1Cqz4MR0LYR8vKpZg/join Follow my second channel: https://www.youtube.com/channel/UCGA2TO8ylVqFHpucwn_6Jlw Follow me on Facebook: https://www.facebook.com/ALLABOUTELECRONICS/ Follow me on Instagram: https://www.instagram.com/all_about.electronics/ Music Credit: http://www.bensound.com$
