13 Δεκ 2023 · Given a number N. The task is to find the sum of the decimal equivalent of all the pairs formed from the binary representation of the given number. Examples: Input: N = 4 Output: 4 Binary equivalent of 4 is 100. All possible pairs are 10, 10, 00 and their decimal equivalent are 2, 2, 0 respectively. So, 2 + 2+ 0 = 4 Input: N = 11 Output: 13 All pos
For example, in binary a three digit decimal number from 0-to-999 requires only 10-bits (1111100111 2), whereas in binary coded decimal, the same number requires a minimum of 12-bits (0011 1110 0111 BCD) for the same representation.
In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Sometimes, special bit patterns are used for a sign or other indications (e.g. error or overflow).
Basics. In computing and electronic systems, binary-coded decimal (BCD) is an encoding for decimal numbers in which each digit is represented by its own binary sequence. Its main virtue is that it allows easy conversion to decimal digits for printing or display and faster decimal calculations.
BCD or binary-coded decimal is a special kind of representation of a decimal number in binary numbers. In binary-coded decimal each individual digit of a number is converted into a binary number, and then by combining them all, the BCD code is generated.
In binary, 0. 2 10 must be approximated. For example, using 16 bits, you could have 0.00110011001100 1 2 , which is 0.19998168945312 5 10 . In BCD, because each digit is encoded separately, an accurate representation is possible.
7 Ιουλ 2023 · This article provides an introduction to the computational number system known as binary-coded decimal or BCD. This numeric encoding scheme is historically significant and still advantageous in certain applications.
