Decrement a TV to obtain 0

Hello,

I need my [[+idx]] tv to start at 0 instead of 1 so i tried this :
[[+idx:decr]] or [[+idx:substract=`1`]] but it gives me -1 (minus one).
Does anyone knows an other way to obtain 0 ?
Thank you

So if you make a listing of each of your notations you get this?
[[+idx]] = 1,2,3,4,5,6
[[+idx:substract=`1`]] = -1,0,1,2,3,4
id that correct?
You could try making a snippet to increment?

and calling it with

Your asp habit is showing

Thank you very much rdaneeel, i've tried to increment with a snippet but it gives me (+)1. It seems like 0 does not exists.
Is there a way to do something like that in a snippet :
