While loops and repeated reduction of a number.

I am trying to write a function file that reduces a given radian such as "7pi" until in its most basic form- between 0 and 2pi. I struggle with while loops for some reason, and this is what I have so far. So if I inputted 7pi I should get out 1pi.
>>n=r-2*pi;
>>While 0<n<2*pi
>> n=r-2*pi;
>>End
I don't know how to structure this, and I need it to work in order to implement a larger script for my project. I'm self taught, so sorry if the above is way off from accurate.

what you are missing from your loop is the updated variable. so what you should have is something like this
Originalr = r;
While 0<r<2*pi
r=r-2*pi;
End
your intial loop did not update so you are just performing the same subtraction over and over 7pi-2pi.

I suggest using the rem function:
r = (1:7)*pi; % Example argument vector
f = rem(r, 2*pi)
produces:
f =
3.1416 0.0000 3.1416 0.0000 3.1416 0.0000 3.1416
