**What Is Exponential In Excel (EXP)?**

*The Exponential in Excel ( EXP) is an inbuilt Math & Trig function. It determines the result of raising the constant e to the power of the specified number. And e is the natural logarithm’s base, with a value of 2.71828.*

*Users can use the Exponential function in Excel when solving expressions containing exponential terms with the base*

**e**.For example, the table below contains the numbers to which we should raise the base **e** to get the required exponential values according to the given descriptions.

Suppose the requirement is to display the result in column C cell range C2:C6. Then, considering the **meaning of Exponential function** explained above, applying the **EXP() **in the target cells can get us the desired outcome.

The **EXP() **in each target cell accepts the corresponding column B **Number** value in the above **example**. And it raises the base **e **to the power of the specified number to return the required exponential value.

For example, the cell C2 formula accepts the cell B2 value, **5**, as the input, and it raises the base **e** to the power **5** to return **148.4131591** as the Exponential function in Excel output.

**number**: The exponent to which we must raise the base**e****using Exponential function in Excel**.

The argument in the EXP function in Excel is mandatory.

Further, the **EXP()** aspects below will help us use the function properly.

- The
**EXP()**argument can only be a number (integers, decimals, fractions). Otherwise, the**EXP()**returns the**#VALUE!**error. And it considers an empty cell value as**0**to return the exponential value of**1**. - The smallest and the largest values the
**EXP()**can accept as input are -1 x 10^{308}and 709.782, respectively. For any number outside this range, the**EXP()**returns the**#NUM!**error. - If the
**EXP()**does not recognize the supplied input as a number, it returns the**#NAME**error. - The
**EXP**function works only for the base**e**. We can use the exponential operator, ‘**^**’, or the**POWER()**for other base values.

**How To Use EXP Excel Function?**

The steps to use the Exponential function in Excel are as follows:

**First, confirm the specified input data is a valid number.****Next, choose the target cell, and enter****EXP**.**Finally, press****Enter**to view the resulting exponential value.

The following **example** shows the above mentioned steps in detail.

The table below contains a list of numbers we require to raise the base **e** to based on the given description.

Suppose the target cells are in the range C2:C6. Then, **using Exponential function in Excel**, we can obtain the desired exponential values for the cell range C2:C6.

**Step 1: **First, select the target cell C2, enter the **EXP()**, and then, press **Enter**.

*=EXP(B2)*

We can also enter the value directly as the **EXP() **argument and get the same output.

*=EXP(2.3)*

Alternatively, we can choose the target cell C2 and navigate through the path **Formulas** – **Math & Trig** – **EXP** to apply the function from the **Formulas** tab.

The above step will open the **Function Arguments** window.

Once we fill in the **Number **field in the **Function Arguments** window, as shown below, and then, click **OK**, we will see the **EXP()** executed in the target cell C2.

**Step 2: **Next, using the fill handle, implement the formula in cell range C3:C6.

Let us consider the cell C6 expression to understand how the formula works. The **EXP()** accepts the cell B6 value, **1/5**, as the **number** argument. It then calculates the base **e** raised to the power** 1/5** and returns the result as **1.221402758**.

### Examples

Check out the following illustrations to understand the **meaning of Exponential function in Excel **and apply the **EXP()** in the best way possible.

**Example #1**

The below table contains the parameter values required to determine the continuous compound interest.

Suppose the requirement is to calculate and display the continuous compound interest in cell C8. Then, here is how applying the EXP function in Excel cell C8 will get us the required result.

**Step 1: **To begin with, select the target cell C8, enter the below formula, and then, press **Enter**.

*=C4*EXP(C5*C6)*

The above expression represents the mathematical formula of continuous compound interest provided in cell A1.

So first, the expression inside the Exponential function in Excel cell C8 multiplies the **r** and **t** values, **10%** and **5**, to return the value** 0.5**. Next, the **EXP()** finds the base **e** to the power **0.5**, which is **1.64872127**. Then the formula multiplies the **EXP()** output with **$1,000** to return the final amount as **$1,648.72**.

**Example #2**

We shall now see how to **plot** **Exponential** **function in Excel**. The following image shows an exponential function in cell B1.

Suppose the value **a** is **0.02 **(refer to cell B2), the x-values are in the table shown in the above image, and the requirement is to determine y-values based on the given x-values.

Assume the target cell range is B5:B14. Then, here is how we can use the **EXP()** in the target cells and then **plot EXP function** to get the desired output.

**Step 1: **First, select the target cell B5. Then, enter the below formula, and press **Enter**.

*=$B$2*EXP(-2*A5)*

**Step 2: **Next, apply the above formula in cell range B6:B14 using the fill handle in excel.

Let us see the cell B14 expression to check how the formula executes. First, the expression inside the Exponential function in Excel cell B14 returns the product of **-2 **and **2 **(cell A14 value), **-4**. Next, the **EXP()** returns the base **e** to the power **-4**, **0.01831563**. Finally, the formula returns the product of **0.02 **and **0.01831563**, **0.000366313**.

**Step 3: **Then, select the cell range A4:B14, go to **Insert** – **Recommended Charts **– **Scatter** to select the **Scatter** chart, and finally, click **OK**.

**Step 4: **Now, right-click on the horizontal axis and then, pick the **Format Axis** option from the contextual menu to open the corresponding window.

**Step 5: **Next, set the **Major** field as **0.2** in the **Format Axis** pane to adjust the horizontal axis scale and close the pane.

**Step 6: **Now, click the **Chart Elements** option (‘**+**’) on the right of the chart area and enable the **Axis Titles** option.

**Step 7: **Then, update the chart and axis titles by selecting the corresponding elements in the chart area.

Thus, the above Scatter plot graphically represents the given Exponential function in Excel.

**Example #3**

We can use the Exponential function in Excel with other inbuilt functions such as **ROUND excel function**.

The below table shows a list of numbers in column A. Column B contains the exponential values obtained by using the EXP function, with the input being the numbers specified in the corresponding column A cells.

Suppose the requirement is to get the exponential values, rounded to **0 **digits, and display the result in column C cell range C2:C6. Then applying the **EXP() **with the **ROUND()** in the target cells will fetch us the required data.

**Step 1: **To begin with, select the target cell C2, enter the below formula, and then, press **Enter**.

*=ROUND(EXP(A2),0)*

**Step 2: **Next, implement the above formula in cell range C3:C6 using the fill handle.

Let us consider the cell C6 expression to see how the formula works. First, the **EXP() **determines the base **e** to the power **1/7**, **1.153564995**. And then, the **ROUND() **rounds up the **EXP()** output to **0 **digits, thus returning the value **1**.

The second argument in the **ROUND() **is **0**. And so, the **EXP **function output gets rounded to the nearest integer.

**Important Things To Note**

- The Exponential function in Excel works only for the base
**e**. - Ensure the number we supply as the
**EXP()**argument is between -1 x 10^{309}and 709.783. Else, the function will return the**#NUM!**error. - Ensure we supply only a number (integer, decimal, or fraction) as the
**EXP**function argument. Else, the function return value will be the**#VALUE!**error. On the other hand, the**EXP**function counts an empty cell as**0**, returning**1**as the exponential value. - For a supplied value not recognized as a number, the
**EXP**function output is the**#NAME**error. Else we might also get a typo error.
