0x1EF

0x1EF is a hexadecimal number, which is a base-16 numeral system used in computing and digital electronics. In hexadecimal, the digits range from 0 to 9 and the letters A to F, where A represents 10, B represents 11, and so on up to F, which represents 15. The prefix "0x" is commonly used to denote a hexadecimal number in programming and digital contexts.

The number 0x1EF can be converted to decimal by breaking it down into its base-16 components. The "1" in the hundreds place represents 1 times 16 squared, the "E" (which is 14 in decimal) in the tens place represents 14 times 16, and the "F" (which is 15 in decimal) in the ones place represents 15 times 1. Adding these together gives 0x1EF = 495 in decimal.

Hexadecimal is widely used in computer science for representing binary-coded values in a more human-readable form. It is particularly useful for tasks such as memory addressing, color coding in web design, and representing machine code instructions. The use of hexadecimal allows for more compact and efficient representation of binary data, making it an essential tool in various fields of technology and engineering.
