10011010

10011010 is an eight-bit binary numeral commonly encountered in computing as a byte. The sequence is read from most-significant bit to least-significant bit (msb to lsb).

Numerical value: in base-2 it equals 154 in decimal; in hexadecimal it is 0x9A. If interpreted as an unsigned byte, the value is 154. In a two's complement 8-bit signed representation, it corresponds to -102.

Character encoding: the value 0x9A lies outside the printable ASCII range (0x00–0x7F). In common extended ASCII encodings it may map to a control code or a glyph depending on the specific encoding. In Unicode, when interpreted as the code point U+009A, it is classified as a control character and is not a standard printable symbol.

Applications: as a bit pattern, 10011010 can be used to enable bits 7, 4, 3, and 1 in a status or control byte, while leaving other bits cleared. It also serves as a typical example of an eight-bit value in teaching materials on bitwise operations, masking, and data representation.
