100111010

100111010 is a nine-bit binary numeral. In unsigned binary it represents the decimal value 314, and in hexadecimal it corresponds to 0x13A. The leftmost bit being 1 places the value above 2^8 (256) in the unsigned interpretation.

In nine-bit two's complement representation, the same bit pattern represents the value -198. This illustrates how the same sequence can have different meanings depending on the chosen numeric interpretation and bit-width.

As a general bit pattern, 100111010 is one of 512 possible nine-bit sequences. Such patterns can occur as memory contents, register values, or subfields within larger instruction encodings in digital systems. There is no widely recognized meaning attached to this exact sequence on its own; its interpretation is entirely context-dependent, shaped by the surrounding bit-width and encoding scheme.

Nine-bit widths are uncommon for standard architectures, which typically use 8, 16, 32, or 64 bits. Nevertheless, nine-bit patterns can arise in specialized hardware designs, microcontrollers with nonstandard register sizes, or as part of larger data structures where a nine-bit field represents a specific flag set or small integer.
