This function returns the square root of the baseToken price quoted in quoteToken, and this data is queried when checking if the vault is in danger in order to liquidate it, with needing a confirmation via PositionCalculator.isLiquidatable(). Extensively, it also is used for all other pricing logics; now it includes an expo, check with has the value of the expo be == - 8.
However, going to the implementation of Pyth natively, i.e., the Pyth Client, we can see that the actual exp value can indeed be negative and positive:
Furthermore, based on a Spearbit discussion with the Pyth team on a previous audit, (see 5.2.2 from [this report](https://github.com/euler-xyz/euler-price-oracle/blob/c4074ab7a7aa0c6ffbc555391d9f0bfe1ee5fd6f/audits/EulerPriceOracleSpearbitReportDRAFT.pdf))_ the Pyth team have confirmed that currently they have set the expo must be -ve check in the SDK to facilitate the discussions, but they do not exclude the fact that this value can be positive in the future.
QA, considering this affects future code; however, this means that valid prices would not be ingested.
Consider supporting positive 8 exp value also for a more generalized integration of the PythOracle.
