0×22

0×22 is a term that can have different meanings depending on context. In mathematics, the symbol × denotes multiplication, so 0 × 22 equals 0. The use of the multiplication sign here emphasizes that, when read as an arithmetic expression, the result is zero.

In computer science and programming, a similar-looking notation 0x22 (with the letter x) is widely used to denote a hexadecimal literal. Some fonts or typographic styles may render the x as a multiplication sign, producing 0×22. The hexadecimal value 0x22 equals 34 in decimal. Hex literals are common in many programming languages for specifying byte values or color codes.

In encoding and character sets, the hexadecimal value 0x22 (or 0x0022 in 16-bit form) corresponds to the quotation mark character. In ASCII, Unicode, and many related encodings, the character with code point U+0022 is the double quotation mark, commonly written as ". In HTML, the same character can be represented by the entity " or by numeric references such as ".

Thus, 0×22 can be a simple arithmetic expression yielding 0, or a hexadecimal representation that encodes the value 34, which in text encoding corresponds to the double quotation mark in ASCII and Unicode. The exact interpretation depends on whether the context uses a multiplication symbol or the hexadecimal prefix convention. See also: 0x22, QUOTATION MARK, ASCII, Unicode.
