Excel provides several math functions to help you perform mathematical tasks easily and swiftly. Today we are going to show you how to use a function called: **RAND**. For the session, we are using Excel 2019, feel free to use yours (at least 2003).

## Excel RAND Function

### 1. Basics of RAND Function

**RAND **is categorized under the **Math & Trig **functions in Excel. This function returns a random number between 0 and 1.

#### Summary

Returns a random number greater than or equal to 0 and less than 1.

#### Syntax

`RAND ()`

#### Arguments

No argument is needed.

#### Versions

Workable from Excel 2003.

### 2. Usage of RAND Function

#### I. Generate Random Numbers Between 0 and 1

From the description of the **RAND **function, you have understood that it’s the basic operation of this function to generate random values between 0 and 1.

To do the task all you need to write

`=RAND()`

Here we have generated 5 random numbers using the **RAND **function. Values are between 0 and 1.

#### II. Generate Random Numbers Between 0 and 100

Apart from numbers between 0 and 1, we can produce random values from 0 to 100.

Our formula will be

`=RAND()*100`

Using the formula, we have generated 5 random values between 0 and 100.

#### III. Generate Random Numbers Between Two Specific Numbers

You can choose your preferred numbers to find random values between them.

Let’s imagine, we have two values, a and b, we will find random values within the range of these two. To find the random values between these two our formula will be

`RAND()*(b-a)+a`

Here we multiply the difference between the two numbers with the random value generated by the **RAND **function. Then add the starting number with that value.

Write the formula replacing a and b with your desired numbers.

Here we have generated random values between 5 and 6.

We can choose any numbers to choose a random value between them.

#### IV. Generate Random Integer Numbers

In most cases, the **RAND **function will generate decimal numbers. If you want to generate integer values then you need to use the **INT function**.

The** INT** function returns the integer part of a decimal number by rounding it down to the integer. To know more about the function visit this INT article.

We will use a nested formula of **INT** and **RAND** combination.

`=INT(RAND()) `

If we write only this, 0 will be generated. Just to show you examples we are aiming to generate numbers between 0 to 100. Then the formula will be

`=INT(RAND()*100)`

Here we have produced 5 random integers between 0 and 100. In place of 100, you can set your preferred number (s).

#### V. Generate Random Numbers Up To Desired Decimal

The **RAND **function emanates random values of decimal numbers. You can set up to which point you want to see decimal values.

Again, we need to use a nested formula, combining the **RAND** function alongside the **ROUND **function.

The **ROUND** function returns a number rounded to a given number of digits. For further information, visit this ROUND function article.

Let’s say that we want to see up to 2 decimal points, then we need to set 2 at the *num_digits *field of **ROUND. **

`=ROUND(RAND()*100,2)`

Here our formula will generate a random value between 0 to 100 with up to 2 decimal points.

Here we have found the value from 0 to 100 with up to 2 decimal points.

You can select your operation with the **RAND **function and choose decimal points depending on the circumstances.

Here we have generated values between different ranges and decimal points.

Similar to the above image, various operations or tasks can be done with **RAND **before using the ROUND function**.**

### 3. Quick Notes

- You can generate random numbers in multiple cells at once. All you need to do is select the cells and write the
**RAND**function.

We have selected two cells here and written **RAND**. And it generated random values in that two cells (image below).

2. Every time you perform a task the random values will be changed. If you don’t want this, then copy the value and paste it as *Paste Values*.

## Conclusion

That’s all for today. We have tried showing how you can use the **RAND** function. You can use the function to find the random values from different ranges as well as in different presentations. Hope you will find this helpful.
