Binary to hexadecimal converter:
A Binary to Hexadecimal Converter is a tool or program that facilitates the conversion of binary (base-2) numbers into hexadecimal (base-16) numbers. In the binary number system, only two digits (0 and 1) are used, while the hexadecimal system employs sixteen digits (0-9 and A-F, where A stands for 10, B for 11, and so on up to F representing 15).
The conversion process involves grouping binary digits into sets of four (since 2^4 = 16) and then finding the corresponding hexadecimal digit for each group. This conversion is commonly used in computing and programming, where binary and hexadecimal are frequently encountered.
For example:
- Binary: 101011
- Grouped into sets of four: 10 1011
- Hexadecimal: 2B
A Binary to Hexadecimal Converter simplifies this process, providing a quick and efficient way to obtain the hexadecimal representation of a binary number. It is a valuable tool for programmers and those working with low-level computing operations.

Explanation
1. HTML Structure:
- The HTML file starts with the basic structure, including a title, input field, button, and a paragraph element to display the result.
2. JavaScript Function:
- Inside the `<script>` tag, there's a JavaScript function named `convert()`.
- This function is triggered when the "Convert" button is clicked.
3. Getting User Input:
- The function retrieves the binary input entered by the user using `document.getElementById('binaryInput').value`.
4. Binary to Decimal Conversion:
- It then converts the binary input to decimal using `parseInt(binaryInput, 2)`. The `2` in `parseInt` indicates that the input is in base-2 (binary).
5. Decimal to Hexadecimal Conversion:
- The decimal result is then converted to hexadecimal using `.toString(16)`. The `16` specifies the base for conversion.
6. Displaying Result:
- Finally, the converted hexadecimal result is displayed in the paragraph element with the id 'result'.
For example, if the user enters "101011" as the binary input:
- Binary to decimal: 101011 in binary is 43 in decimal.
- Decimal to hexadecimal: 43 in decimal is 2B in hexadecimal.
The displayed result would be "Hexadecimal Result: 2B". The `toUpperCase()` is used to ensure that the hexadecimal result is in uppercase letters for consistency.
This simple HTML and JavaScript code demonstrate the fundamental process of converting binary to hexadecimal within a web page.
