0b1000111

0b1000111 is a binary literal, a notation used in some programming languages to express a number in base-2. Its value in decimal is 71; in hexadecimal, it is 0x47; in octal, it is 0o107.

The bit pattern consists of seven bits: from most significant to least: 1 0 0 0 1 1 1. This corresponds to 2^6 + 2^2 + 2^1 + 2^0 = 71, so it has bits set at positions 0, 1, 2, and 6.

In ASCII, decimal 71 corresponds to the uppercase letter G. In 7-bit ASCII, 71 lies within the standard 0–127 range, representing the character G when interpreted as a character code.

In programming practice, 0b1000111 can be used as a constant in expressions, in bitwise operations, or as a teaching example illustrating binary-to-decimal conversion. Languages that support binary literals commonly use the 0b prefix to indicate base-2 notation, such as Python and JavaScript; some compilers for C and related languages also provide this syntax or equivalents.

Other representations of the same value include hexadecimal 0x47 and octal 0o107. The binary form is often preferred for illustrating bit patterns and masks, while hex and octal forms can be more compact for manual reading or documentation.
