Question Everything is moving exactly by 1 space when using axis in my unity

Hey everyone I am facing some weird issues while I was using unity, I was working on a 3d level and it was all working fine then suddenly when I am trying to move like a tile in my level it's moving by 1 space/distance instead of like in some decimal or how much I pull my axises arrowes, maybe I clicked somewhere by mistake, I really have no clue how did this happened please if u guys know any solution or how this happened i would be grateful

The video that I recorder so u could understand more properly

 

You seem to have enabled it with the second blue icon just above the game screen.

 

yeah it got fixed thanks a lot..
