I don't understand why you use strings and Cdbl function for such an easy example? Could you explain the reasoning? Thanks, good video

[TeachMeUp]

@AndyBCankaya Because new users have to know what these functions do, ofcourse these codes I am writing can be very short and simple, but new users have to know what is happening and what functions there are in VB. That's why I chose to use these functions and make it longer than is needed!

And thanks!
