0x45B

0x45B is a hexadecimal integer literal used in many programming languages to denote a base-16 value. When interpreted as a decimal number, 0x45B equals 1115. In binary, it is 10001011011 (or 010001011011 when shown as a 12-bit value).

In programming, the 0x prefix signals hexadecimal notation. For example, in C or C++, int a = 0x45B; assigns the value 1115 to a. In JavaScript, var a = 0x45B; similarly yields the decimal 1115. In Python, a = 0x45B is valid and, after evaluation, hex(a) returns '0x45b'. Some SQL dialects that support hex literals treat 0x45B as a numeric constant or binary data, depending on the dialect’s rules.

0x45B by itself does not reference a widely known standard or entity; it is simply a numeric constant that can appear in code, data, or documentation. It is also unrelated to HTML or CSS color codes, which use a leading '#' and a different notation (for example, #45B in CSS expands to #4455BB). In contexts such as memory addressing or bitwise operations, 0x45B may be used as a small example value to illustrate concepts like masking or offset calculations.
