How do you describe decile?

How to calculate the rank of a decile?
There are several formulae in vogue to calculate decile, and this method is one of the simplest one where each decile is calculated by adding one to the number of data in the population, then divide the sum by 10 and then finally multiply the result by the rank of the decile i.e. 1 for D 1, 2 for D 2 … 9 for D 9. ……………………………………
