# HEX to Decimal

## Unlock the power of HEX to Decimal conversion! Simplify your coding, debugging, and memory addressing with this essential guide. Click to master it now!

**Introduction:**

The **HEX to Decimal **conversion is a fundamental concept in computing, crucial for various programming and electronic applications. HEX (hexadecimal) is a base-16 numbering system used in digital systems, while Decimal is the standard base-10 system. Understanding how to convert between these systems is essential for tasks like debugging, memory addressing, and low-level programming.

**Demonstration:**

Consider the HEX number `1A3F`. To convert it to Decimal:

1. Break down the HEX number into individual digits: `1`, `A`, `3`, and `F`.

2. Convert each digit to Decimal: `1` (1), `A` (10), `3` (3), `F` (15).

3. Apply the positional values: \(1 \times 16^3\), \(10 \times 16^2\), \(3 \times 16^1\), \(15 \times 16^0\).

4. Sum the results: \(1 \times 4096 + 10 \times 256 + 3 \times 16 + 15 \times 1 = 6719\).

**Usage:**

Use HEX to Decimal conversion in programming by employing functions like `parseInt("1A3F", 16)` in JavaScript or `int("1A3F", 16)` in Python. These functions simplify the process, enabling quick and accurate conversions for various applications.

**Conclusion:**

Mastering HEX to Decimal conversion is vital for developers and engineers. It ensures efficient handling of data in different numeral systems, enhancing problem-solving skills and technical proficiency.
