1110010100012

111001010001, written with a base-2 indicator in many contexts as 111001010001₂, is a binary numeral. It consists of 12 bits. As an unsigned integer, it equals 3665 in decimal and 0xE51 in hexadecimal. The bit pattern begins with a run of three ones, followed by two zeros, then a one, a zero, a one, and ends with three zeros and a final one.

If interpreted as a signed 12-bit two's complement value, it represents -431. This is because values from 0x800 to 0xFFF in 12-bit two's complement represent negative numbers, and 0xE51 corresponds to 0x1000 less than zero, i.e., 3665 - 4096 = -431.

In computing and digital electronics, binary strings of this length and structure can serve as data values, bit masks, addresses, or opcode patterns, depending on the context and encoding scheme. The specific sequence 111001010001 may arise as a fixed constant or as part of a larger bitstream used to convey information at the bit level.
