0x122

0x122 is a hexadecimal literal representing the number 290 in decimal notation. The prefix “0x” indicates that the following digits are in base sixteen, a convention widely used in computer science and programming languages such as C, C++, Java, and JavaScript. Each digit in a hexadecimal value corresponds to four binary bits, allowing compact representation of binary data and ease of conversion to and from binary and decimal forms.

In many contexts, 0x122 may appear as an example in documentation for learning binary arithmetic or converting between bases. For instance, to convert 0x122 to binary, each digit is expanded to its four‑bit sequence: 1 → 0001, 2 → 0010, 2 → 0010, yielding 0001 0010 0010, which equals decimal 290. Likewise, 290 divided by 16 results in quotient 18 and remainder 2, confirming the hexadecimal value of 0x122.

Hexadecimal values also appear in color specifications in web design, where each pair of digits encodes a color channel. Although 0x122 would be interpreted as a 24‑bit color code 0x01 22 (though typically six digits are used), it can also serve as an example in networking, where hexadecimal numbers denote IP addresses, memory addresses, or protocol identifiers. Consequently, 0x122 serves as a teaching tool to illustrate base‑conversion techniques and the relevance of hexadecimal notation in digital systems.
