0xB19

0xB19 is a string formatted with the 0x prefix that denotes hexadecimal notation. In hex, the digits B, 1, and 9 correspond to decimal values 11, 1, and 9, respectively. The value of the hex literal 0xB19 is 2841. The prefix 0x is standard in many programming languages to indicate that the literal that follows should be interpreted as a base-16 number.

As a literal, 0xB19 can appear in source code as a numeric constant, a bit mask, an index, or any place where a hex value is appropriate. The 0x prefix is common in languages such as C, C++, JavaScript, Python, and many others.

In other contexts, the string may appear as part of longer identifiers, memory addresses, cryptographic keys, or domain-specific codes. On its own, 0xB19 is not known to refer to a widely recognized object, and its meaning is dependent on context. For example, Ethereum-style addresses are 40 hex digits long after the 0x prefix, so 0xB19 would not be a valid full address; it might appear as a short form, a display fragment, or as part of a larger identifier.
