# Why does the price input automatically round to a seemingly random number?

**When providing liquidity, your input min and max price will always automatically round to the nearest tick.**

Under the hood, the Astar Exchange v3 protocol divides prices up into discrete intervals known as ‘ticks’. These ticks use logarithmic space.

The size of the tick is a function of the fee tier — generally, the tick is double the size of the fee tier (e.g. a tick for a 0.30% fee tier pool will be 0.60% in size and there will be a tick every price 1.006^n where n is an integer and price is the relative price between token0 and token1).

As an example, take an LP that wishes to deposit into the WETH/USDC pool with a 0.30% fee tier. The LP would like to provide liquidity within a range of 1,000 to 5,000.

The nearest available ticks in this instance are 1,155 (1.006^1155 = 1,001.538) and 1,424 (1.006^1424 = 5,006.388), so the LPs price inputs will be automatically rounded to 1,001.538 and 5,006.388.
