1101111010

1101111010 is a 10‑bit binary numeral. When interpreted as an unsigned binary value it equals eight hundred and fifty‑eight in decimal notation (0x35A in hexadecimal). The binary string can also be parsed as a two’s complement signed integer; in that representation the leading ‘1’ indicates a negative value, yielding –698 in decimal. Because it consists of ten bits, it can represent values in the range 0 to 1023 (unsigned) or –512 to 511 (two’s complement). In many early computer systems and embedded devices a 10‑bit word length was common, so the pattern 1101111010 could appear as a data word in memory, a machine code instruction, or a control signal.

In digital logic design the pattern may be used as a test vector or a known‑good code to verify proper propagation through logic gates. The sequence also contains a run of three consecutive ones (111) followed by a run of two zeros (00) and then three more ones (111), a characteristic that can be exploited in pattern‑matching algorithms.

On the Internet, the sequence can be used as a unique identifier or hash fragment in documentation or code repositories where a short, non‑alphanumeric string is desirable. Though it has no special semantic meaning beyond its mathematical representation, 1101111010 serves as a useful example when teaching binary to decimal conversion or the representation of signed numbers in two’s complement.
