[Newbie] problem with divide values

Hi ! first of all, i think it's a simple problem for you but I did not find the solution by searching on roll20. Maybe i'm a newbie too to find a tips ^^' So this is my problem :   i want to implement this calculation : floor(@{Agility]-5/2)+floor(@[Agility]-5/10)+1  But when I tried, I had a bad result. So I decided to split the calculation and I find this : <input type="number" name="attr_Agility" value="5" /> ==> Agility : 5 <input type="number" name="attr_Agmod" value="@{Agility}-5" disabled="true" /> ==> Default : 0 <input type="number" name="attr_Agfloory" value="floor(@{Agmod}/2)" disabled="true" /> ==> Default : obtain 2 <input type="number" name="attr_Agfloorz" value="floor(@{Agmod}/10)" disabled="true" /> ==> Default : obtain 4 <input type="number" name="attr_Agility_mod" value="@{Agfloorz}+@{Agfloory}+1" disabled="true" /> ==> So, in deed, i obtain 7 Someone can explain where where I was wrong ?

It looks like you have some syntax errors where you have square bracket where squiggly one should be.  Also the way you have the computation in the inputs you should have the formula, floor(@{Agility}/2-5/2)+floor(@{Agility}/10-5/10)+1 

The problem doesn't changed when you split the calculation. =/

I don't know.  It's working for me.  I tested the floor function with random attributes from 5E OGL and all works as intended.  

Ania, can you paste the code for the input you are using?

Finally, i have found a another way. floor(@{Agility}*0.596-2.525) It's works and it's no complex. Thanks for your help ^^
