0xa63

0xA63 is a hexadecimal integer literal used in many programming languages to denote a specific numeric value. The 0x prefix marks hexadecimal notation, so 0xA63 represents the decimal value 2659.

Numeric representation: The hex digits A, 6, and 3 correspond to the values 10, 6, and 3. In binary this is 1010 0110 0011. When stored in memory, 0xA63 occupies at least 12 bits; in common computer architectures it is represented within larger integer types (such as 16-, 32-, or 64-bit integers) with leading zeros.

Usage in code: In languages with C-style syntax—C, C++, Java, JavaScript, and Python—0xA63 is parsed as an integer literal. Examples: in Python, x = 0xA63 assigns 2659 to x. In C, unsigned int x = 0xA63; also yields 2659. Such literals are widely used for constants, bitmasks, and addressing constructs in low-level programming and systems code.

Origin and context: The 0x prefix originates from the C language, which popularized hexadecimal literals. The convention has been adopted by many modern languages and tools. Hex literals are commonly used when configuring hardware registers, parsing binary protocols, or expressing color-related values in some contexts.

Notes: Hex digits are 0–9 and A–F (case-insensitive). 0xA63 can also be written as 0xa63.
