3735928559

3735928559 is the decimal representation of the 32-bit unsigned integer 0xDEADBEEF. The hexadecimal form is widely recognized in computing and is often cited as a “magic number” used for debugging, memory testing, and diagnostic markers.

The hex digits DEADBEEF form the mnemonic phrase “dead beef,” which contributes to its memorability in programming culture. The four bytes are 0xDE, 0xAD, 0xBE, and 0xEF. As a result, the value functions as a recognizable pattern in code samples, memory dumps, and development tools.

Usage and significance: DEADBEEF is commonly employed as a sentinel value to mark uninitialized or freed memory, to identify special data structures, or to fill blocks during debugging allocations. It helps developers quickly spot data that has not been properly written or memory that has been overwritten. The pattern appears in various languages and environments, including C and C++, in the form of macros, initialization patterns, or crash-dump markers.

Endianness note: while the 32-bit value is 0xDEADBEEF, the byte order in memory can vary with architecture. On little-endian systems the bytes appear as EF BE AD DE in memory, though the logical value remains 3735928559. This distinction matters when inspecting raw memory or performing low-level debugging.
