10100111

10100111 is an eight-bit binary numeral. In the binary numeral system, it represents a specific pattern of bits used in digital data, computing, and various encoding schemes. As a standalone string, it does not identify a single standard concept but can be interpreted in several common ways depending on context.

As a numeric value, 10100111 represents the unsigned integer 167. This equals 128 + 32 + 4 + 2 + 1, and is commonly written in hexadecimal as 0xA7. If interpreted as a signed eight-bit integer using two's complement, the most significant bit being 1 indicates a negative value, yielding -89 (since 256 - 167 = 89).

In text encoding, the byte 0xA7 corresponds to the section sign symbol (§) in ISO/IEC 8859-1 (Latin-1) and in Unicode (U+00A7). In UTF-8, the same code point is encoded differently as 0xC2 0xA7 when used within Unicode text, rather than as a single byte.

In other technical contexts, 10100111 can function as a bit mask or a field value within a byte. The set bits occur at positions 7, 5, 2, 1, and 0, which may be significant in low-level programming, hardware registers, or protocol flags.

Overall, 10100111 is best understood as a concise binary pattern whose meaning depends on how the eight bits are interpreted—unsigned versus signed numeric value, character encoding, or bitwise usage in software and hardware.
