Function: isSqrtPriceInRange
isSqrtPriceInRange(
sqrtPrice,tickLower,tickUpper):boolean
isTickInRange for a pool's square-root price instead of its tick (a position row that
carries sqrtPrice, tickLower and tickUpper). The tick is derived from the price exactly as
the contract does (sqrtPriceToTick: the greatest tick whose square-root price is no greater
than the price, exact to 60 digits), then the contract's rule applies: lower tick inclusive,
upper tick exclusive. So a pool sitting exactly on tickLower's price is in range, and exactly
on tickUpper's price is not, and no float rounding can flip either.
false for a price that is not positive and finite (not loaded, zero, NaN): it says nothing
about the position, so an app that must show a neutral state checks for the missing price
itself first. tickLower and tickUpper follow isTickInRange.
