0x3D3

0x3D3 is the hexadecimal numeral for the decimal value 979. The prefix 0x is standard in many programming languages, including C, C++, Java, JavaScript, and Python, to denote a base-16 literal. Therefore, 0x3D3 equals decimal 979, and conversely 979 in decimal is represented as 0x3D3 in hex.

In binary, 0x3D3 corresponds to 0011 1101 0011 (a 12-bit pattern), which can be written more compactly as 1111010011 when leading zeros are omitted. In octal, the same value is 1723. In 16-bit or larger contexts, the value is represented as 0x03D3, occupying the lower 12 bits.

In memory, the two-byte representation of the 16-bit value 0x03D3 can differ by endianness. On big-endian systems, it is stored as 03 D3; on little-endian systems, it is stored as D3 03. This matters for low-level programming tasks such as memory dumps and network byte order conversions.

In programming pedagogy, 0x3D3 is commonly used as an example hex constant to illustrate numeric bases, bitwise operations, and endianness. It does not carry special mathematical significance beyond being a representative, moderately sized constant for instructional purposes.
