0x10000000

0x10000000 is a hexadecimal numeric literal used in computing to denote the integer 268,435,456. In binary, it equals 1 shifted left 28 places (2^28). This makes it equal to 256 mebibytes, i.e., 268,435,456 bytes.

In practice, 0x10000000 is commonly seen as a memory address boundary or a size constant in 32-bit and 64-bit systems. It can denote the start of a mapped region, a block size for memory allocation, or a mask boundary in bitwise operations. Because it is a power-of-two boundary, it is convenient for alignment and page-table calculations in low-level code.

In programming languages such as C, C++, Java, and JavaScript, 0x10000000 is a valid integer literal and is typically interpreted as a 32-bit (or larger) integer value, depending on the language and type suffixes used. It is often favored in examples and documentation as a clean, round boundary value for illustrating memory maps, offsets, and alignment concepts.
