 Price fractions are never directly returned by the interface. Instead, the oracle acts as though it is quoting swap amounts. This avoids certain catastrophic losses of precisions, especially with low-decimal tokens (see [an example with SHIB/USDC](https://github.com/euler-xyz/euler-price-oracle/blob/master/docs/whitepaper.md#precision-loss-example)).
 
-Price oracles may legitimately return `0` to indicate that a requested quote amount is worthless, either because the price is very low or the quote amount was very small, or both. Legitimate pricing errors are signalled by a the oracle reverting. This in turn causes the vault to revert, which is dangerous since it can break functionality of the vault (most importantly, liquidation). Because of this, only reliable pricing oracles should be used.

 The `getQuote` function returns how many `quote` tokens an `inAmount` of `base` tokens would purchase at the current marginal (no price impact) price. The `getQuotes` method (plural) may return both the bid and ask `quote` amounts for the specified quantity of `base`. Although simple oracles will return the same amounts for both bid and ask, more advanced vaults may use this to expose current market spreads. Alternatively, confidence intervals can be expressed, potentially by querying multiple oracles, sorting them, and returning the lowest amount as the bid and the highest as the ask.
