The VBA SQR function is listed under the math category of VBA functions. When you use it in a VBA code, it returns the square root of the number supplied. In simple words, you can calculate the square root of a number with it.




  • Number: A number for which you want to calculate the square root.


To practically understand how to use the VBA SQR function, you need to go through the below example where we have written a vba code by using it:

Sub example_SQR()
Range("B1").Value = Sqr(Range("A1"))    
End Sub

In the above code, we have used the SQR to get the square root of the value that we have in cell A1 (625) it has returned 25 which is the square root of 625 in cell B1.
