3. **Outline the Article Content:**
- **Introduction (as per rules):**
- Start with 3-4 compelling questions about converting numbers, the purpose of DEC2OCT, its syntax, and practical uses.
- Follow with the introductory paragraph promising to cover all these points and introducing the `DEC2OCT` function.
- **`
` – فرمول DEC2OCT در گوگل شیت چیست و چه کاربردی دارد؟**
- Explain the concept of number systems (decimal vs. octal) simply.
- Define the function: it converts base-10 to base-8.
- Discuss its primary applications: programming, computer science, data encoding, working with legacy systems, permissions in Unix-like systems (e.g., `chmod`). This adds significant value.
- **`
` – ساختار و آرگومانهای فرمول DEC2OCT**
- Break down the syntax: `DEC2OCT(decimal_number, [significant_digits])`
- Create an HTML `
` to explain each argument:
- `decimal_number`: (عدد دهدهی) – Required. Explain constraints (e.g., integer, range).
- `significant_digits`: (ارقام مهم) – Optional. Explain what it does (padding with leading zeros) and its purpose.
- **`
` – آموزش گام به گام استفاده از فرمول DEC2OCT**
- A simple, numbered list (`
- `) showing how to use the formula from scratch.
- Step 1: Open Google Sheets.
- Step 2: Select a cell.
- Step 3: Type `=DEC2OCT(`.
- Step 4: Enter the decimal number or cell reference.
- Step 5: Optionally add the `significant_digits` argument.
- Step 6: Close the parenthesis and press Enter.

- This section is crucial for demonstrating value.
- `
` – مثال ۱: تبدیل شناسههای کاربری (User IDs) برای سیستمهای قدیمی`
`
Create a small scenario where a company needs to interface with an older system that uses octal IDs. Show the before-and-after in a table.
- `
` – مثال ۲: محاسبه و تنظیم سطوح دسترسی (Permissions) فایل`
`
This is a classic use case. Explain how Unix/Linux file permissions (like `755`) are octal representations of binary flags. Show how to convert the decimal sum of permissions to the octal code using `DEC2OCT`.
سطح دسترسی (دهدهی) فرمول کد دسترسی (اکتال) 493 `=DEC2OCT(493)` 755 - `
` – مثال ۳: استفاده از آرگومان [significant_digits] برای قالببندی`
`
Show how using the optional argument helps in creating standardized, fixed-length octal codes. For example, converting `10` to `012` instead of `12` by using `DEC2OCT(10, 3)`.

- `
` – ترکیب با `IF` برای تبدیل شرطی`
`
Example: `=IF(A2>0, “کد اکتال: ” & DEC2OCT(A2), “مقدار نامعتبر”)`. This adds a layer of logic.
- `
` – ترکیب با `ARRAYFORMULA` برای پردازش یک ستون کامل`
`
Show how to apply the conversion to an entire range at once without dragging the formula down. `=ARRAYFORMULA(IF(ISNUMBER(A2:A), DEC2OCT(A2:A), “”))`
- **`
` – اشتباهات رایج و نحوه رفع آنها**
- Create a `
- ` list of common errors.
- **خطای `#NUM!`:** Explain why it happens (input number is too large/small, non-integer, or invalid `significant_digits`). Provide solutions.
- **خطای `#VALUE!`:** Occurs when the input is text instead of a number. Solution: ensure the input is numeric.
- **خروجی غیرمنتظره:** Explain that the output is a string, not a number, and cannot be used in direct mathematical calculations without conversion back (e.g., using `OCT2DEC`).

` – مقایسه DEC2OCT با توابع تبدیل مبنای دیگر**
- Use a `
` for a clear comparison.
- Columns: `تابع (Function)`, `تبدیل از (From)`, `تبدیل به (To)`, `کاربرد اصلی (Primary Use)`.
- Rows: `DEC2OCT`, `OCT2DEC`, `DEC2BIN`, `DEC2HEX`. This provides context and cross-links to related knowledge.
