0x

0x is a prefix used to indicate that a number is in hexadecimal (base 16) notation. It is commonly used in programming and computing contexts to differentiate hexadecimal numbers from decimal (base 10) numbers.

Examples:

  • 0x1A represents the decimal number 26.
  • 0xFF represents the decimal number 255.
  • 0x10 represents the decimal number 16.

Use cases:

  • Defining colors in web design: #FF5733 can be represented as 0xFF5733 in some programming languages.
  • Memory addresses in programming languages such as C or C++: 0x00400000 might represent a specific address in memory.
  • Working with binary data or protocols that require hexadecimal representation.
