[PD] [array quantile] explanation

Hi all

I am having difficulty understanding the output of [array quantile].
From the help-file it seems it expects an input between 0 and 1, and
also the values in the array should be in that range. The output seems
to be in the range between 0 and <array-size> - 1. But what does it
mean?

Can I use this somehow to achieve this:

I have n samples and input q while 0 < q < 1. I would like to know the
value x for which q*100 percent samples are smaller than x and (1-
q)*100 percent bigger. 

Thanks, 
Roman
