0x21F0

0x21F0 is a hexadecimal numeric literal used in computing to denote the integer value equal to decimal 8688. The prefix 0x is a common convention in many programming languages, such as C, C++, Java, JavaScript, Python, and others, to indicate that the number that follows is in base 16. Hex literals are often used to express binary patterns, bit masks, memory addresses, or opcodes because each hexadecimal digit represents four binary bits.

The value 0x21F0 has the binary representation 0010 0001 1111 0000, which helps in bitwise operations and masking tasks. In different contexts, 0x21F0 can be interpreted differently: as a numeric constant in code, as a memory address in a low-level program, or as a Unicode code point in text processing.

In Unicode, the code point U+21F0 falls within the Arrows block and is used to indicate an arrow symbol. The exact glyph depends on the font and rendering system; not all fonts include the same glyphs for nearby code points.

Because 0x21F0 is simply a number in hex, its meaning is determined by the surrounding context: software, hardware registers, protocol fields, or data formats may assign specific significance to the value 0x21F0 beyond its decimal equivalent.
