0x200000000

0x200000000 is a hexadecimal integer literal used in programming and computing. The prefix 0x denotes base-16 notation, and the following digits specify a particular power-of-two value.

Value and magnitude: 0x200000000 equals 2 × 16^8, which is 2^33, or 8,589,934,592 in decimal. In binary, this value corresponds to a single 1 bit at position 33 with all lower bits zero. It also corresponds to 8 gibibytes (8 GiB), or 8,589,934,592 bytes, when interpreted as a size in memory.

Size and representation: Because it equals 2^33, it requires 34 bits to represent exactly. On most systems, it cannot be stored in a 32-bit unsigned integer (which maxes at 2^32−1, or 4,294,967,295) and instead requires 64-bit types or larger.

Usage and context: As a power-of-two constant, 0x200000000 is commonly seen in contexts involving bitwise operations, memory addressing, or size specifications that involve large offsets or boundaries. Its value being exactly 8 GiB makes it a natural reference point when discussing memory capacity, file sizes, or address space in systems that adopt binary-based units.

Related values: A nearby hex constant is 0x100000000, which equals 2^32 (4,294,967,296 decimal). The value 0x200000000 is exactly twice that amount.
