0x1000000000

0x1000000000 is a hexadecimal integer constant. In hexadecimal notation, it is 1 followed by nine zeros, representing the value 16^9. This equals 2^36, which in decimal is 68,719,476,736. In terms of bytes, the quantity corresponds to 64 gibibytes (64 GiB), since 2^36 bytes equal 64 × 2^30 bytes.

In computing, 0x1000000000 is often used to denote a size or boundary that lies beyond the 32-bit range, because the maximum unsigned 32-bit value is 0xFFFFFFFF (4,294,967,295). As such, this constant appears in contexts involving 64-bit integers, memory allocation limits, file size representations, or address arithmetic where larger address spaces are relevant.

The literal uses the 0x prefix to indicate hexadecimal notation, a convention common in C-family languages and many programming tools. In code, 0x1000000000 can be written as a shift expression such as (1 << 36) in languages that support bit shifting, highlighting its interpretation as 2^36.

Summary: 0x1000000000 denotes the value 2^36 (68,719,476,736), equivalent to 64 GiB. It is a representative constant used to express large sizes or addresses beyond 32-bit limits in software and systems programming.
