0xE1F

0xE1F is a hexadecimal numeric literal commonly used in computer programming and digital electronics. The prefix 0x denotes that the digits that follow are in base 16, rather than decimal. Interpreted as a single unsigned integer, 0xE1F equals 3615 in decimal. In binary, it corresponds to the 12-bit pattern 1110 0001 1111, which would be padded with leading zeros in wider word sizes (for example, 0000 0000 0000 0000 0000 1110 0001 1111 in a 32-bit representation).

Usage and contexts

- In many programming languages (such as C, C++, Java, and C#), 0xE1F can be used wherever an integer literal is allowed, for example: int x = 0xE1F; or const int y = 0xE1F; In JavaScript, 0xE1F is treated as a number with the value 3615.

- Such literals are common for writing bit masks, immediate values in low-level code, or convenient hexadecimal constants in algorithms and data structures.

Notes and distinctions

- 0xE1F is a value, not a character. Unicode code points are typically written as U+XXXX (for example U+0E1F), and should not be conflated with 0xE1F unless the context explicitly maps hex literals to a Unicode code point.

- While 0xE1F is valid in many languages, its size and signedness can depend on the language and type context.
