0x1A8B

0x1A8B is a hexadecimal number. In decimal representation, it is equal to 6795. The prefix "0x" indicates that the number is expressed in base 16. Hexadecimal notation is commonly used in computing, particularly in representing memory addresses, color codes, and other data where a compact representation of binary information is desired.

The digits in a hexadecimal number range from 0 to 9 and A to F, where A represents 10, B represents 11, and so on, up to F representing 15. Therefore, 0x1A8B can be broken down as follows: 1 * 16^3 + A * 16^2 + 8 * 16^1 + B * 16^0. Substituting the decimal values for A (10) and B (11), this becomes 1 * 4096 + 10 * 256 + 8 * 16 + 11 * 1, which equals 4096 + 2560 + 128 + 11, resulting in the decimal value of 6795.

Understanding hexadecimal numbers is crucial for various fields within computer science and programming, allowing for a more efficient way to read and write binary data compared to its direct binary or lengthy decimal equivalent. The specific significance or context of 0x1A8B would depend entirely on where it appears, such as a memory address, an identifier, or a configuration parameter within a specific software or hardware system.
