How can squareroot price change without changing tick?

[@smartcontractprogrammer]

ticks increment by tick spacing for example if tick spacing is 10, during a swap the active tick would move but the change may be less than tick spacing

@@smartcontractprogrammer Thanks for reply. I wonder why the tick spacing is being used? What is the purpose of introducting tick spacing.
