16b00001111

16b00001111 is a textual form sometimes encountered in documentation or sample data to denote a 16-bit binary literal. The prefix can be interpreted as “16-bit binary,” followed by the bit pattern 00001111. When read as a 16-bit value with leading zeros, the full binary representation is 00000000 00001111.

This yields the hexadecimal value 0x000F and the decimal value 15. In many contexts, such a pattern is used to illustrate basic binary encoding, bitwise operations, or the effects of masking and shifting. The representation emphasizes that only the least-significant bits contain ones, while the more-significant bits are zeros.

In memory, the 16-bit value 0x000F occupies a single low byte of 0x0F and a high byte of 0x00. The byte order in memory depends on endianness: in little-endian systems it is stored as 0x0F 0x00, while in big-endian systems it is stored as 0x00 0x0F. Such distinctions are commonly discussed in topics related to data representation and systems architecture.

Not a standardized notation, 16b00001111 is context-dependent and may appear in various forms in different languages or tools. Readers should interpret it considering the surrounding documentation to determine whether it represents a literal value, a textual label, or a sample bit pattern.
