0x7EF4

0x7EF4 is a hexadecimal number. In decimal representation, it is equal to 32500. The notation "0x" indicates that the following digits are in base 16. This means the number is composed of digits from 0 to 9 and letters A to F, where A represents 10, B represents 11, C represents 12, D represents 13, E represents 14, and F represents 15.

To convert 0x7EF4 to decimal, we multiply each digit by the corresponding power of 16 and sum the results. The rightmost digit (4) is multiplied by 16^0 (which is 1), the next digit (F or 15) by 16^1 (which is 16), the next digit (E or 14) by 16^2 (which is 256), and the leftmost digit (7) by 16^3 (which is 4096). Therefore, the calculation is (7 4096) + (14 256) + (15 16) + (4 1) = 28672 + 3584 + 240 + 4 = 32500.

Hexadecimal notation is commonly used in computing and programming. It is a more human-readable way to represent binary data than pure binary, as it requires fewer digits. For example, a 16-bit value that might be represented as 1111111011110100 in binary can be more compactly represented as 0x7EF4 in hexadecimal. This numerical value, 32500, could represent various things depending on the context, such as a memory address, a color code, or a part of a larger data structure.
