0x21EF

0x21EF is a hexadecimal numeral commonly used in computing. It represents the integer value 8687 in decimal. In binary it is 0010 0001 1110 1111, and in hex it is written as 0x21EF. The prefix 0x indicates a base-16 literal, a convention used in many programming languages such as C, C++, Java, JavaScript, and Python.

In practical software development, 0x21EF can appear as a numeric constant in code, often serving as a memory address, a bit mask, or part of a data encoding or low-level operation. Its interpretation is context-dependent and is determined by how the surrounding program uses the value. For example, as a color code it could be part of a larger 24-bit value, or as a flag set it could occupy specific bit positions within a register.

If interpreted as a Unicode code point, 0x21EF corresponds to the code point U+21EF. This places it within the Unicode Arrows block, which spans from U+2100 to U+21FF. The exact glyph for U+21EF depends on the font and rendering system, so the character shown may vary between environments. In any case, the code point is a character selector independent of the numeric value 8687 unless the context explicitly maps one to the other.

Notes:

- 0x21EF equals 8687 decimal.

- In languages with 16-bit or larger integers, it fits comfortably within typical signed and unsigned ranges.

- When referring to the Unicode point, consult a Unicode chart for the precise glyph and name.
