It seems there might be a bit of confusion in your question. If you're asking about the international standard for numbering systems, there isn't a single "international number system" per se. However, there are different numbering systems used globally for various purposes. Here are a few notable examples:

  1. Decimal Number System:
    • This is the most common numbering system and is widely used internationally. It is a base-10 system where each digit can take values from 0 to 9.
  2. Binary Number System:
    • Used extensively in computing, the binary system is base-2, with digits 0 and 1.
  3. Octal Number System:
    • Octal is a base-8 numbering system. It is occasionally used in computing but less common than binary and hexadecimal.
  4. Hexadecimal Number System:
    • Hexadecimal is a base-16 numbering system. It is widely used in computing, especially in programming and digital electronics.
  5. Roman Numerals:
    • Roman numerals are an ancient numbering system that was widely used in the Roman Empire and is still used today in various contexts, such as numbering book chapters, movie sequels, and clock faces.
  6. International Mobile Subscriber Identity (IMSI):
    • IMSI is a unique identifier associated with a mobile subscriber. It is used in mobile networks worldwide.
  7. International Standard Book Number (ISBN):
    • ISBN is a unique identifier for books, recognized internationally. Each edition and variation of a book receives a unique ISBN.
  8. International Standard Serial Number (ISSN):
    • Similar to ISBN, ISSN is a unique identifier for periodicals (such as magazines and journals).

If you are referring to a specific system not covered by the examples above, please provide more details or clarify your question so that I can better assist you.
