100110010001002

100110010001002 is a short, finite string used in discussions of numeral systems and formal languages. It consists of 15 digits drawn from the alphabet {0, 1, 2} and ends with the digit 2. The sequence is not a binary number because it contains the symbol 2, but it can be interpreted as a numeral in base 3.

As a base-3 numeral, the string represents the decimal value 5,021,381. This is obtained by summing each digit multiplied by 3 raised to its position power, counting from the rightmost digit as position zero. The interpretation as a base-3 number highlights how strings containing digits beyond binary can encode larger numeric values within a familiar positional system.

In theoretical contexts, 100110010001002 is used as a representative example word over the non-binary alphabet {0, 1, 2}. It serves to illustrate concepts in formal language theory, such as tokenization, pattern matching, and parsing, where different alphabets and terminators can affect recognition and processing rules. The final 2 can be construed as a potential terminator or delimiter in some modeling scenarios, though there is no universal standard for this particular string.

Overall, 100110010001002 functions primarily as an instructional or demonstrative object in discussions of numeral systems and automata, rather than as a widely adopted identifier or encoding standard. See also binary numeration, base-3 numeration, and formal language theory.
