My mouse moves one unit when I'm trying to extrude or move object

I need some quick hellp please.

My mouse moves 1.00 unit or more when i try to exrude or move object, it doesn’t allow me to move 0.01 (only if i insert from keyboard). It just jumps to 1.0 or 3.0 or some other natural value. It allows me to move normaly only if i keep the Alt key pressed.

What can I do to solve this problem?

Turn off snapping

It worked. I’m new to blender thx for the help!
