**Part 2: Examples**

๐ **Example 1: Determining the Sign of Sales Profit**

**Purpose**: To determine if the sales profit is positive, negative, or neutral.**Data Sheet and Formulas**:A B C 1 Sales Profit SIGN Formula Result 2 500 =SIGN(A2) 1 3 0 =SIGN(A3) 0 4 -200 =SIGN(A4) -1 **Explanation**: In this example, a favorable sales profit returns 1, zero profit returns 0, and a negative profit returns -1.

๐ **Example 2: Checking the Sign of Inventory Difference**

**Purpose**: To check if the inventory difference is positive, negative, or zero.**Data Sheet and Formulas**:A B C 1 Inventory Diff. SIGN Formula Result 2 30 =SIGN(A2) 1 3 0 =SIGN(A3) 0 4 -15 =SIGN(A4) -1 **Explanation**: This helps businesses quickly identify if there’s an excess or shortage in inventory.

๐ **Example 3: Analyzing Monthly Balance**

**Purpose**: To analyze whether the monthly balance is surplus, deficit, or neutral.**Data Sheet and Formulas**:A B C 1 Monthly Bal. SIGN Formula Result 2 1000 =SIGN(A2) 1 3 0 =SIGN(A3) 0 4 -500 =SIGN(A4) -1 **Explanation**: This helps in financial analysis to quickly gauge the financial health for the month.

๐ **Example 4: Evaluating Daily Transactions**

**Purpose**: To evaluate whether the daily transactions are profitable, lost, or neutral.**Data Sheet and Formulas**:A B C 1 Daily Trans. SIGN Formula Result 2 150 =SIGN(A2) 1 3 0 =SIGN(A3) 0 4 -75 =SIGN(A4) -1 **Explanation**: This helps businesses quickly identify the transaction status in daily analysis.

๐ **Example 5: Checking Loan Differences**

**Purpose**: To check if the loan differences are positive, negative, or zero.**Data Sheet and Formulas**:A B C 1 Loan Diff. SIGN Formula Result 2 2000 =SIGN(A2) 1 3 0 =SIGN(A3) 0 4 -1000 =SIGN(A4) -1

**Explanation**: This helps financial institutions quickly gauge the loan status.

๐ **Example 6: Using SIGN with IF to Determine Profit or Loss**

**Purpose**: To determine if the sales difference indicates a profit, loss, or break-even.**Data Sheet and Formulas**:A B C 1 Sales Diff. Formula Result 2 500 =IF(SIGN(A2)=1, “Profit”, “Loss”) Profit 3 0 =IF(SIGN(A3)=0, “Break-even”, “Loss”) Break-even 4 -200 =IF(SIGN(A4)=-1, “Loss”, “Profit”) Loss **Explanation**: This formula helps businesses quickly determine if they made a profit, lost, or broke even based on the sales difference. The SIGN function is used to get the sign of the sales difference, and the IF function interprets the result.

๐ **Example 7: Using SIGN with SUM to Calculate Net Sales**

**Purpose**: Calculate net sales and determine whether they’re positive, negative, or neutral.**Data Sheet and Formulas**:A B C D 1 Sales Jan Sales Feb Formula Result 2 1000 -500 =SIGN(SUM(A2:B2)) 1 3 500 -500 =SIGN(SUM(A3:B3)) 0 4 -200 100 =SIGN(SUM(A4:B4)) -1 **Explanation**: By summing the sales of January and February, businesses can quickly determine the net sales sign using the SIGN function.

๐ **Example 9: Using SIGN with COUNTIF to Analyze Feedback**

**Purpose**: To determine the overall sentiment of feedback received.**Data Sheet and Formulas**:A B C 1 Feedback Formula Result 2 Positive =SIGN(COUNTIF(A2:A4, “Positive”)) 1 3 Neutral =SIGN(COUNTIF(A2:A4, “Neutral”)) 0 4 Negative =SIGN(COUNTIF(A2:A4, “Negative”)) -1 **Explanation**: By counting the occurrences of each feedback type, businesses can quickly gauge the overall sentiment using the SIGN function.

๐ **Example 10: Using SIGN with ROUND to Determine Rounded Values**

**Purpose**: To determine the sign of rounded sales values.**Data Sheet and Formulas**:A B C 1 Sales Formula Result 2 499.5 =SIGN(ROUND(A2, 0)) 1 3 0.3 =SIGN(ROUND(A3, 0)) 0 4 -499.5 =SIGN(ROUND(A4, 0)) -1 **Explanation**: The ROUND function rounds the sales values, and the SIGN function determines the sign of the rounded values.

๐ **Example 11: Using SIGN with ABS to Analyze Absolute Sales Differences**

**Purpose**: To determine the sign of absolute sales differences.**Data Sheet and Formulas**:A B C 1 Sales Diff. Formula Result 2 -500 =SIGN(ABS(A2)) 1 3 0 =SIGN(ABS(A3)) 0 4 200 =SIGN(ABS(A4)) 1 **Explanation**: The ABS function returns the absolute value of the sales difference, and the SIGN function determines its sign. This helps in scenarios where only the magnitude of the difference matters, not its direction.

๐ **Example 12: Using SIGN with INT to Determine Integer Parts**

**Purpose**: To determine the sign of the integer part of sales values.**Data Sheet and Formulas**:A B C 1 Sales Formula Result 2 499.5 =SIGN(INT(A2)) 1 3 0.3 =SIGN(INT(A3)) 0 4 -499.5 =SIGN(INT(A4)) -1 **Explanation**: The INT function extracts the integer part of the sales values, and the SIGN function determines its sign. This helps when businesses want to analyze only the whole number part of their sales data.
