0x8000000

0x8000000 is a hexadecimal integer literal commonly used in computing. It represents the decimal value 134,217,728, which is 2^27. In binary, this value is a 1 followed by 27 zeros (1<<27). In 32-bit notation, it is often written as 0x08000000, with the same numeric value.

As a single-set-bit value, 0x8000000 is frequently used as a bitmask or flag in low-level programming. When included in a 32-bit word, it marks the bit at position 27, allowing code to test, set, or clear that specific flag without affecting other bits.

The constant also relates to memory and size calculations. Since 2^27 bytes equals 134,217,728 bytes, this value is equivalent to 128 mebibytes (128 MiB). Consequently, 0x8000000 can appear in contexts involving memory allocation, addressing boundaries, or data structure sizing where powers of two are relevant.

Summary: 0x8000000 denotes 134,217,728 (2^27), commonly appearing as a bitmask in software and as a size reference in memory calculations. Its hexadecimal form is frequently aligned to 0x08000000 in eight-digit representations, but both forms denote the same value.
