How to test if the remainder is a decimal or an integer?

[GerdW]

Hi Craster,

did you notice the ready-to-use example by Christian?

And please don't use the word "decimal", when you are talking about "fractional" numbers…

Yes I have made the appropriate changes. 

Thanks a lot everyone!

I again apologise for asking so basic questions, and that too with wrong terminologies.

Really appreciate the help.
