In this Salesforce tutorial, we will learn about the **ABS() function** and how we can use it to **calculate the absolute value of numerical data**. In addition, we will also focus on **its syntax** and some **practical examples**.

While working in a **Sales Organization** that uses Salesforce as a customer relationship management tool to track their sales. I got a task to **calculate the difference between target sales and actual sales**.

Here I found an **ABS() function** in Salesforce that helped me to calculate the absolute difference. Now, let us discuss in detail, how to use the **Salesforce ABS() function** to calculate the absolute value of a number in **Salesforce Lightning as well as Salesforce Classic**.

## What is ABS() function in Salesforce

In Salesforce, we have multiple functions that are used to perform mathematical calculations and the **ABS() function** is one of the mathematical functions.

This **ABS() function** is used to calculate the absolute value of a number. The absolute value represents the magnitude of a number without considering its sign.

In layman’s terms, the **ABS() function** is used to calculate the absolute number which gives the **positive value of a number** as a result without considering whether the original number was positive or negative.

Moreover, we should be kept one thing in mind the **ABS() function** works only on numeric data types such as Decimal, Integer, or Double. If you use it with other data types such as text, date, or other non-numeric data types it will produce an error.

### Syntax and Usage of ABS() function in Salesforce

The syntax of the ABS() function is given below:

`ABS(number/field/formula)`

The **number/field/formula** parameter is the value for which we wish to determine the absolute value. The value specified in the parameter can be a field, a numeric constant, or a formula.

Let’s see an example to clearly understand the concept and syntax of the **ABS() function**.

Suppose, we want to calculate the absolute value of the numeric field value called **“Net Profit” **and for this, we use the **ABS()** function and calculate it. The formula is as follows:

`ABS(Net Profit)`

With this, we have understood the **ABS() function with its syntax, important points, and example**. Now, we will move and try to understand the **steps to calculate the absolute value in Salesforce Lightning**.

## How to calculate the absolute value in Salesforce Lightning

Here, are the steps to calculate the absolute value in Salesforce Lightning:

**1: **First, log in to Salesforce Lightning mode and navigate to the right corner of the page, then click on the **“Gear Icon”** (⚙). Now, from the dropdown menu (⬇) click on the **“Setup”**.

**2: **From the left side of the menu, click on **“Object Manager”**.

**3: **Search for the object in the search bar where we wish to utilize the **ABS() function**. In this case, I search for the **“Opportunity”** object as I want to track the sales.

**4:** Now, click on the **“Opportunity”** object and it will redirect us to the ** Opportunity Page**.

**5:** From the left side of the page click on the **“Field & Relationship”** option.

**6:** Click on the **“New”** button to create a new field where we can use the **“ABS() function”**.

**7:** It will redirect to the **“Choose the field type” **page, now check the radio button in front of the **“Formula”** data type.

**8:** To proceed to the next step, click on the **“Next”** button.

**9: **Enter the **“Field Label”** for the formula and the unique **“Field Name”** will be automatically populated. In this case, I entered the field label named **“Absolute Sales Variance”**.

**10:** Choose the **“Data Type”** for the field for which we want to calculate the absolute value. Make sure the data type must be of a numeric type such as “**Number**“, “**Currency**“, etc.

In this case, I check the radio button in front of the **“Currency”** to set it as the formula return type.

**11:** Now, to move to the next step click on the **“Next”** button.

**12:** Move to the advance formula editor, and enter the formula that uses the **ABS() function** to calculate the absolute value.

In this case, I want to calculate the absolute value of the sales variance i.e. the difference between target sales and actual sales using the ABS() function. Here, is the formula:

`ABS(Target_Sales__c - Actual_Sales__c)`

- In this formula, we subtract the
**“Actual_Sales__c”**field from the**“Target_Sales__c”**field. - Then we use the
**ABS() function**with it to calculate the absolute value of the difference between actual sales and target sales.

**13:** Click on the **“Check Syntax”** button to validate the formula and ensure that there are no errors.

**14:** Optionally, we can **“Handle the empty field” **as well as we can define the **“Description”** and **“Help text”** if we want.

**15:** Click on the **“Next”** button to move ahead.

**16:** Choose the appropriate field **“Level Security”**. Here, I check the **“Visible”** checkbox as I want it to be visible to all. Then, click on the **“Next”** button.

**17:** Now, select the appropriate **“Page Layout”** where we want to be visible.

**18:** Lastly, click on the **“Save”** button to save the formula field.

We can use the formula field once we’ve created it. Let’s look at an example:

- Open the
**Opportunity Tab**and create a**New Opportunity**with the fields**Target Sales**and**Actual Sales**. - After that, click on the
**Details**section, and here the**Absolute Sales Variance**field appears which shows you the result of the**ABS() function**.

As a result, we now know **how to calculate the absolute value in Salesforce Lightning.** Now, we’ll look at how to calculate the absolute value in Salesforce Classic.

## How to calculate the absolute value in Salesforce Classic

Here, are the steps to calculate the absolute value in Salesforce Classic:

**1:** From the Salesforce Lightning to open your Salesforce Classic edition. Click on** Avtar** and then click **Switch to Salesforce Classic**.

**2: **After that, click on the **Setup** option.

**3: **Now, scroll down to the **Build** section. Then under **Customize**, select the object for whom field we want to use the** ABS()** function. In this case, I select the **“Cases”** object as I want to track the response time.

**4:** Click on the **“Cases”** dropdown and select the** “Fields”** option to get the option of the new field.

**5:** Now scroll down to the **“Custom Fields & Relationships”** and click on the **“New”** button to create a new formula field.

**6:** It will redirect to the **“Choose the field type” **page, now check the radio button in front of the **“Formula”** data type.

**7:** To proceed to the next step, click on the **“Next”** button.

**8: **The unique **“Field Name”** will be filled out automatically when you enter the **“Field Label”** for the formula. I entered **“Response Time Variance”** into the field labeled in this instance.

**9:** Select the **“Data Type**” for field that we want to calculate the absolute value. Make sure the data type must be of a numeric type such as **“Number**“, **“Currency**“, etc.

In this case, I check the radio button in front of the **“Number**” to set it as the formula return type. I also set the decimal place to 0.

**10:** Now click the **“Next”** button to go to the next step.

**11: **Move to the advance formula editor, and enter the formula that uses the **ABS() function** to calculate the absolute value.

In this case, I want to calculate the absolute value of the response time variance i.e. the difference between target response time and initial response time using the **ABS() function**. Here, is the formula:

`ABS(Target_Response_Time__c - Initial_Response_Time__c)`

- In this formula, we subtract the
**“Target_Response_Time__c**” field from the**“Initial_Response_Time__c”**field. - Then we use the
**ABS() function**with it to calculate the absolute value of the difference between the target response time and the initial response time.

**12: **To check the formula and make sure there are no mistakes, click the **“Check Syntax”** option.

**13: **Optionally, we can define the **“Description”** and **“Help text”** as well as **“Handle the empty field”** if we prefer.

**14:** Click on the **“Next”** button to move ahead.

**15:** Select the relevant **“Level Security” **field. I have selected **“Visible” **in this case because I want it to be visible to everyone. Following that, select **“Next”** to move ahead.

**16:** Now, select the appropriate **“Page Layout”** where we want this field to be visible.

**17:** Lastly, click on the **“Save”** button to save the formula field.

We can use the formula field once we’ve created it. Let’s look at an example:

- Open the
**Case Tab**and create a**New Case**with the fields**Target Response Time**and**Initial Response Time**. - On Save, it will redirect us to the
**Detail**page, and here the**Response Time Variance**field appears which shows us the result of the**ABS() function**.

As a result, we now know **how to calculate the absolute value in Salesforce Classic.**
