# View functions and helpers

> Read-only functions shared by the current Q128.128 execution paths.

The core program exposes five views.

## `view_sqrt_price_at_tick_x128`

Returns the canonical Q128.128 square-root price for a tick.

## `view_swap_iteration`

Runs one initialized-tick walk step from a `SwapIterCfg`, tick hint, target price, `Tick`, and `SwapIterState`. It returns the next state and tick value.

## `view_mul_div`

Runs the shared full-width `u256` multiply-divide helper. The caller selects floor or ceiling rounding.

## `resolve_stored_tick`

Resolves the stored tick after the crossing loop and bounded partial fill. It preserves the half-open range convention when execution rests at an initialized tick.

## `view_bounded_partial`

Consumes remaining input only up to the nearer next initialized tick or price limit. It returns the next square-root price, remainder, output, fee growth, protocol fee, and estimated tick.

The function returns all input when fee-adjusted input floors to zero. It also avoids an uncrossed upward rest exactly at an initialized tick, which would desynchronize stored liquidity and price.

Views share contract arithmetic. They do not bypass bounds, rounding, or overflow checks. Bind any off-chain simulation to a specific state snapshot.
