0x38

0x38 is a hexadecimal numeral that represents the decimal value 56. In binary, it is 00111000. The prefix 0x is widely used in computing to indicate that the following digits are in base 16, which is common in programming, encoding, and data representation.

In computing, 0x38 can appear in various contexts as a literal byte value. It commonly appears in code samples, data dumps, and low-level programming where exact byte values are important. Because hexadecimal notation is compact and aligns with byte boundaries, 0x38 is often encountered when dealing with bit patterns, memory addresses, or protocol fields that specify numeric values.

A notable context for 0x38 is the Ethereum Virtual Machine (EVM). In the EVM, the byte value 0x38 is the opcode for CODESIZE, which pushes the size of the currently executing contract’s code onto the stack. This opcode is part of the range of opcodes used for interacting with the contract’s code, alongside operations like CODECOPY and CODEHASH. The presence of 0x38 as an opcode means it contributes to how smart contracts can inspect and manipulate their own bytecode at runtime, influencing control flow and self-inspection logic.

Beyond these contexts, 0x38 is simply a common hexadecimal value that may appear in data, addresses, or code that use hex notation. Its meaning is determined by the surrounding context in the software or protocol being described.
