Have you ever ever heard of hexadecimal? If not, you then’re lacking out on an entire new approach of studying numbers. Hexadecimal, or hex for brief, is a base-16 quantity system that makes use of 16 distinctive characters to symbolize the numbers 0 by 15. This is usually a little bit complicated at first, however when you get the grasp of it, you can learn hex numbers as simply as you learn decimal numbers.
Probably the greatest issues about hex is that it is a very compact option to symbolize numbers. For instance, the decimal quantity 255 might be written as FF in hex. It is because 255 is similar as 11111111 in binary, and 11111111 is similar as FF in hex. As you may see, hex is a way more compact option to write this quantity than decimal.
Hex can be utilized in quite a lot of functions, together with pc programming, net design, and digital artwork. In pc programming, hex is used to symbolize reminiscence addresses and different knowledge values. In net design, hex is used to symbolize colours. In digital artwork, hex is used to symbolize the colours of pixels. As you may see, hex is a really versatile quantity system that can be utilized in quite a lot of functions. In case you’re occupied with studying extra about hex, there are a variety of sources accessible on-line. You can too discover tutorials on YouTube that may train you how you can learn and write hex numbers.
Understanding the Fundamentals of Hexadecimal
Relating to computer systems, all the things boils all the way down to binary code, a collection of 0s and 1s that inform the pc what to do. Nevertheless, working with binary code might be tedious and error-prone, particularly when coping with giant numbers. That is the place hexadecimal (hex) is available in.
Hex is a base-16 quantity system that makes use of 16 digits as an alternative of the ten digits utilized in decimal (base-10). The 16 hex digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. Every hex digit represents a particular mixture of 4 binary digits (bits). The connection between hex and binary is proven within the desk under:
| Hex Digit | Binary Equal |
|---|---|
| 0 | 0000 |
| 1 | 0001 |
| 2 | 0010 |
| 3 | 0011 |
| 4 | 0100 |
| 5 | 0101 |
| 6 | 0110 |
| 7 | 0111 |
| 8 | 1000 |
| 9 | 1001 |
| A | 1010 |
| B | 1011 |
| C | 1100 |
| D | 1101 |
| E | 1110 |
| F | 1111 |
Through the use of hex, we will symbolize giant binary values in a extra compact and readable format. This makes it simpler to work with and debug code, particularly when coping with reminiscence addresses, colour codes, and different numeric knowledge.
Decoding Hexadecimal Values
Hexadecimal values are decoded by changing every digit to its corresponding binary equal. That is achieved by utilizing a desk that reveals the binary equal of every hexadecimal digit.
For instance, the hexadecimal digit “A” is decoded because the binary worth “1010”.
Desk of Hexadecimal Digits and Their Binary Equivalents
| Hexadecimal Digit | Binary Equal |
|---|---|
| 0 | 0000 |

| C | 1100 |
| D | 1101 |
| E | 1110 |
| F | 1111 |
To decode a hexadecimal worth, merely convert every digit to its binary equal utilizing the desk above. Then, concatenate the binary equivalents to kind the binary illustration of the hexadecimal worth.
For instance, to decode the hexadecimal worth “A5”, we might convert “A” to “1010” and “5” to “0101”. Concatenating these binary equivalents provides us the binary illustration of “A5”, which is “10100101”.
Changing Hexadecimal to Decimal
Changing hexadecimal to decimal is a comparatively simple course of that includes multiplying every hexadecimal digit by its place worth after which including the merchandise collectively. The place values for hexadecimal digits are 16n, the place n is the place of the digit from proper to left, beginning with 0. The hexadecimal digits and their corresponding decimal place values are proven within the following desk:

| 1 | 161 = 16 |
| 2 | 162 = 256 |
| 3 | 163 = 4,096 |
| 4 | 164 = 65,536 |
| 5 | 165 = 1,048,576 |
| 6 | 166 = 16,777,216 |
| 7 | 167 = 268,435,456 |
| 8 | 168 = 4,294,967,296 |
| 9 | 169 = 68,719,476,736 |
| A | 1610 = 1,099,511,627,776 |
| B | 1611 = 17,592,186,044,416 |
| C | 1612 = 281,474,976,710,656 |
| D | 1613 = 4,503,599,627,370,496 |
| E | 1614 = 72,057,594,037,927,936 |
| F | 1615 = 1,152,921,504,606,846,976 |
For instance, to transform the hexadecimal quantity 5A to decimal, we first multiply every hexadecimal digit by its place worth:
5 × 161 = 80
A × 160 = 10
Then we add the merchandise collectively:
80 + 10 = 90
Subsequently, the decimal equal of 5A is 90.
