Learn how to use the Excel RND function with syntax and examples.
The Microsoft Excel RND function allows you to generate a random number (integer value). You can specify the random number to be a value between 2 user-specified numbers.
The syntax for the Microsoft Excel RND function is:
Int ((upperbound - lowerbound + 1) * Rnd + lowerbound)
upperbound is the highest value that the random number can be.
lowerbound is the lowest value that the random number can be.

The RND function can be used in Microsoft Excel as the following type of function:
The RND function can only be used in VBA code in Microsoft Excel.
Let's look at some Excel RND function examples and explore how to use the RND function in Excel VBA code:
Int ((6 - 1 + 1) * Rnd + 1) Result: random number between 1 and 6 Int ((200 - 150 + 1) * Rnd + 150) Result: random number between 150 and 200 Int ((999 - 100 + 1) * Rnd + 100) Result: random number between 100 and 999
Dim LRandomNumber As Integer LRandomNumber = Int ((300 - 200 + 1) * Rnd + 200)
In this example, the variable called LRandomNumber would now contain a random number between 200 and 300.
