Binary Number Notation

Binary notation is a base-2 numeral system that uses only two digits: 0 and 1. Each digit in a binary number represents a power of 2. Binary is fundamental in computing and digital electronics, where data is represented using bits (binary digits).

Hexadecimal Number Notation

Hexadecimal notation is a base-16 numeral system that uses 16 digits: 0-9 and A-F (where A=10, B=11, C=12, D=13, E=14, and F=15). Hexadecimal is often used due to its concise representation of binary values. In byte representation, each hexadecimal digit corresponds to four bits (half a byte). Bytes are commonly represented as pairs of hexadecimal digits. Each digit in a hexadecimal number represents a power of 16.To distinguish from decimal numbers, hexadecimals are often prefixed with "0x" or “x”.

Binary to Hexadecimal Conversion

To convert a binary number to hexadecimal, group binary digits into sets of four (starting from the right) and then replace each group with its hexadecimal equivalent.

Example:

Let's convert the binary number 1101101011011011 to hexadecimal.

Separating into groups of 4 bits: 
1101 1010 1101 1011

Replacing each group with its hexadecimal equivalent:
D A D B

So, 1101101011011011  is equal to DADB.

Binary to Hexadecimal Conversion in Programming Languages

Here are examples of binary to hexadecimal conversion functions in various programming and scripting languages:

C/C++:

Use strtol to convert binary to decimal and then print the result in hexadecimal using %X.

#include ‹stdio.h ›
#include ‹stdlib.h ›
int main() {
    char binaryNumber[] = "1101101011011011";
    long decimalNumber = strtol(binaryNumber, NULL, 2);
    char hexResult[20];
    sprintf(hexResult, "%lX", decimalNumber);
    printf("%s\n", hexResult); // Output: DADB
    sprintf(hexResult, "%#lX", decimalNumber);
    printf("%s\n", hexResult); // Output: 0XDADB
    return 0;
}

Java:

Utilize Integer.parseInt to convert binary to decimal and then format the result in hexadecimal using %X.

public class BinaryToHexadecimal {
    public static void main(String[] args) {
     String binaryNumber = "1101101011011011";
     int decimalNumber = Integer.parseInt(binaryNumber, 2);
     String hexResult = String.format("%X", decimalNumber);
     System.out.println(hexResult); // Output: DADB
    }
}

PHP:

Employ bindec for binary to decimal conversion and dechex for hexadecimal formatting.

$binaryNumber = "1101101011011011";
$decimalNumber = bindec($binaryNumber);
$hexResult = strtoupper(dechex($decimalNumber));
echo $hexResult . "\n"; // Output: DADB

Python:

Use int for binary to decimal conversion and hex for hexadecimal formatting.

binaryNumber = “1101101011011011”
decimalNumber = int(binaryNumber, 2)
hexResult = hex(decimalNumber)[2:].upper()
print(hexResult)  # Output: DADB

Ruby:

Convert binary to decimal using to_i and then format the result in hexadecimal.

binaryNumber = “1101101011011011”
decimalNumber = binaryNumber.to_i(2)
hexResult = decimalNumber.to_s(16).upcase
puts hexResult  # Output: DADB

JavaScript:

Utilize parseInt for binary to decimal conversion and toString for hexadecimal formatting.

let binaryNumber = "1101101011011011";
let decimalNumber = parseInt(binaryNumber, 2);
let hexResult = decimalNumber.toString(16).toUpperCase();
console.log(hexResult); // Output: DADB

Perl:

Use oct for binary to decimal conversion and sprintf to format the result in hexadecimal.

my $binaryNumber = "1101101011011011";
my $decimalNumber = oct("0b$binaryNumber");
my $hexResult = sprintf("%X", $decimalNumber);
print "$hexResult\n"; # Output: DADB

PowerShell:

Utilize [Convert]::ToInt64 for binary to decimal conversion and ToString for hexadecimal formatting.

$binaryNumber = “1101101011011011”
$decimalNumber = [Convert]::ToInt64($binaryNumber, 2)
$hexResult = $decimalNumber.ToString("X")
Write-Output $hexResult # Output: DADB

Excel/Google Sheet Function for Binary to Hexadecimal Conversion

In Excel or Google Sheets, you can use the BIN2HEX function for binary to hexadecimal conversion. 

BIN2HEX(signed_binary_number, [significant_digits])

Where: 

• signed_binary_number - the binary number you want to convert. Number cannot contain more than 10 characters (10 bits).
• significant_digits - the number of characters to use. The result will be padded with leading 0s (zeros) if required.
