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

Sub example_EXP()
Range("B1").Value = Exp(Range("A1"))    
End Sub

In the above example, we have used EXP and the supplied value of x from cell A1 and it has returned the value of the exponential function ex 4.05519996684467 in cell B1.
