0xE58

0xE58 is a hexadecimal numeric literal used in many programming and scripting languages. The 0x prefix indicates base-16 notation, so 0xE58 represents the integer whose hexadecimal digits are E, 5, and 8. In decimal, this value is 3672. In binary, it corresponds to 0000 1110 0101 1000 in a 16-bit representation.

Commonly, 0xE58 appears in code wherever a precise numeric value is needed, such as defining constants, setting bitmasks, or representing memory addresses and offsets. In languages like C, C++, Java, JavaScript, and Python, you can assign or compare with 0xE58 just as with any other integer literal.

Notes and caveats:

- The 0x prefix is a convention in many programming languages to denote hexadecimal, and the digits inside may be written in upper or lower case (A–F are valid either way).

- The value’s width depends on the language and variable type; 0xE58 fits within 16 bits and is commonly used as a small constant or mask.

- In web design, hexadecimal color values are also common, but CSS uses the format #rgb or #rrggbb without a 0x prefix. For example, #E58 is treated as shorthand and expands to #EE5588, whereas 0xE58 would not be recognized as a color in CSS.

Origin: The 0x prefix originated in C and has since become standard in many languages to distinguish hexadecimal literals from decimal numbers.
