0xE03

0xE03 is a hexadecimal numeric literal that may appear in software, hardware, and documentation to denote a specific integer value. In base-16 notation, it consists of the digits E, 0, and 3. The decimal equivalent is 3587. The prefix 0x is a common convention in many programming languages to indicate that the following digits are hexadecimal.

In programming, 0xE03 is used as a constant value. For example, in C or C++, a declaration like int code = 0xE03; assigns the value 3587 to code. The practical interpretation of the value depends on the surrounding context, including the variable type (signed or unsigned) and the width of the integer type. It can be stored in 8-, 16-, 32-, or 64-bit integers depending on the language and compile-time settings.

Common contexts where 0xE03 may appear include representing enumerated values, bit masks, or identifiers for hardware registers in low-level programming. It may also appear in configuration data, protocol fields, or diagnostic outputs where hexadecimal notation is used to convey compact numeric information. The exact meaning of 0xE03 is not universal and is defined by the specific specification, API, or hardware documentation in which it appears.

Pitfalls to consider include the fact that leading zeros can be omitted, so 0x0E03 and 0xE03 represent the same value. Endianness affects how the value is stored in memory but not its numeric value. Depending on the context, a hex literal may be treated as unsigned or signed, which could influence interpretation if the value is examined as a signed integer.
