When you’re keen on studying extra about hex, there are a selection of sources obtainable on-line. You may also discover tutorials on YouTube that may train you 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 sequence of 0s and 1s that inform the pc what to do. Nonetheless, working with binary code may 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 selected 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, coloration codes, and different numeric knowledge.
Decoding Hexadecimal Values
Hexadecimal values are decoded by changing every digit to its corresponding binary equal. That is accomplished through the use of a desk that exhibits 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 |
| 1 | 0001 |
| 2 | 0010 |

| 7 | 0111 |
| 8 | 1000 |
| 9 | 1001 |
| A | 1010 |
| B | 1011 |
| 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 offers us the binary illustration of “A5”, which is “10100101”.
Changing Hexadecimal to Decimal
Changing hexadecimal to decimal is a comparatively easy 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:
| Hexadecimal Digit | Decimal Place Worth |
|---|---|
| 0 | 160 = 1 |
| 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.
