0x493E0

0x493E0 is a hexadecimal numeral commonly used in computing to denote a specific integer value. The literal consists of the digits 4, 9, 3, E, and 0, preceded by the 0x prefix that signals base-16 notation.

Interpreted as decimal, 0x493E0 equals 300,000. In binary, it corresponds to 00000000 00000100 10010011 11100000 when represented as a 32-bit value, or more compactly as 01001001001111100000 in its 20-bit form. In 32-bit hexadecimal form it is written as 0x000493E0, which aligns with common memory and data-size conventions in programming.

In software development, hexadecimal literals like 0x493E0 are frequently used to express memory addresses, offsets, bit masks, or constant values in source code. They are language-agnostic in concept, though syntax varies by language; in many languages, the 0x prefix designates a hex integer. The numeric value remains the same regardless of endianness, though the in-memory byte order may differ depending on the system architecture.

Properties of the value include that it is a multiple of 16, since the least significant hex digit is 0. This can be relevant in contexts involving alignment, block sizes, or certain hardware interfaces where powers-of-two boundaries are convenient.
