 * The default value of {decimals} is 18. To change this, you should override
 * this function so it returns a different value.
 *
 * We have followed general OpenZeppelin Contracts guidelines: functions revert
 * instead returning `false` on failure. This behavior is nonetheless
 * conventional and does not conflict with the expectations of ERC20
 * applications.
 *
 * Additionally, an {Approval} event is emitted on calls to {transferFrom}.
 * This allows applications to reconstruct the allowance for all accounts just
 * by listening to said events. Other implementations of the EIP may not emit
 * these events, as it isn't required by the specification.

/**
 * @notice Adapted Uniswap V3 OracleLibrary computation to be compliant with Solidity 0.8.x and later.
 *
 * Documentation for Auditors:
 *
 * Solidity Version: Updated the Solidity version pragma to ^0.8.0. This change ensures compatibility
 * with Solidity version 0.8.x.
 *
 * Safe Arithmetic Operations: Solidity 0.8.x automatically checks for arithmetic overflows/underflows.
 * Therefore, the code no longer needs to use SafeMath library (or similar) for basic arithmetic operations.
 * This change simplifies the code and reduces the potential for errors related to manual overflow/underflow checking.
 *
 * Overflow/Underflow: With the introduction of automatic overflow/underflow checks in Solidity 0.8.x, the code is inherently
 * safer and less prone to certain types of arithmetic errors.
 *
 * Removal of SafeMath Library: Since Solidity 0.8.x handles arithmetic operations safely, the use of SafeMath library
 * is omitted in this update.
 *
 * Git-style diff for the `consult` function:
 *
 * ```diff
 * function consult(address pool, uint32 secondsAgo)
 *     internal
 *     view
 *     returns (int24 arithmeticMeanTick, uint128 harmonicMeanLiquidity)
 * {
 *     require(secondsAgo != 0, 'BP');
 *
 *     uint32[] memory secondsAgos = new uint32[](2);
 *     secondsAgos[0] = secondsAgo;
 *     secondsAgos[1] = 0;
 *
 *     (int56[] memory tickCumulatives, uint160[] memory secondsPerLiquidityCumulativeX128s) =
 *         IUniswapV3Pool(pool).observe(secondsAgos);
 *
 *     int56 tickCumulativesDelta = tickCumulatives[1] - tickCumulatives[0];
 *     uint160 secondsPerLiquidityCumulativesDelta =
 *         secondsPerLiquidityCumulativeX128s[1] - secondsPerLiquidityCumulativeX128s[0];
 *
 * -   arithmeticMeanTick = int24(tickCumulativesDelta / secondsAgo);
 * +   int56 secondsAgoInt56 = int56(uint56(secondsAgo));

 *     // Always round to negative infinity
 * -   if (tickCumulativesDelta < 0 && (tickCumulativesDelta % secondsAgo != 0)) arithmeticMeanTick--;
 * +   if (tickCumulativesDelta < 0 && (tickCumulativesDelta % secondsAgoInt56 != 0)) arithmeticMeanTick--;
