This change fixes floating point errors in conversion of shares to assets and other way, used in `VaultDeposit`, `VaultWithdraw` and `VaultClawback`. In the floating point calculations the division introduces a larger error than multiplication. If we do division first, then the error introduced will be increased by the multiplication that follows, which is therefore the wrong order to perform these two operations. This change flips the order of arithmetic operations, which minimizes the error.
- A regular payment that is late, or a tfLoanLatePayment that is not
late will fail.
- Flags are mutually exclusive.
- Add a few interest computation shortcuts and overflow prevention
checks that return 0 if there's no time to compute for.
This change fixes JSON parsing of negative `int` input in `STNumber` and `STAmount`. The conversion of JSON to `STNumber` or `STAmount` may trigger a condition where we negate smallest possible `int` value, which is undefined behaviour. We use a temporary storage as `int64_t` to avoid this bug. Note that this only affects RPC, because we do not parse JSON in the protocol layer, and hence no amendment is needed.
- Assert requires that an overpayment reduces the value of a loan. If
the overall loan interest is low enough, it could leave it unchanged.
Update the assert to require that the overpayment does not increase
the value of the loan.
- Adds a unit test provided by @gregtatcam to demonstrate this issue.
* mywork/ximinez/lending-number:
Add a distinction between a "valid" and a "representable" Number
chore: Point xrpld symlink to rippled (6012)
Catch up the consequences of Number changes
Fix build error - avoid copy
Add integer enforcement when converting to XRP/MPTAmount to Number
Make all STNumber fields "soeDEFAULT"
Add optional enforcement of valid integer range to Number
- "valid" means the value is <= Number::maxIntValue, which has been
changed to maxMantissa / 100. A valid number could get bigger and be
ok - such as when paying late interest on a loan.
- "representable" means the value is <= Number::maxMantissa. An
unrepresentable number WILL be rounded or truncated.
- Adds a fourth level of enforcement: "compatible". It is used for
converting XRP to Number (for AMM), and when doing explicit checks.
- "weak" will now throw if the number is unrepresentable.
- Vault and LoanBroker pseudo-accounts can hold MPTs, regardless of MPTRequireAuth setting.
- Add requireAuth check in LoanBrokerCoverDeposit and LoanPay.
- Fail attempts to unauthorize pseudo-accounts by MPT issuers.
- Change the Number::maxIntValue to all 9's.
- Add integral() to Asset (copied from Lending)
- Add toNumber() functions to STAmount, MPTAmount, XRPAmount to allow
explicit conversions with enforcement options.
- Add optional Number::EnforceInteger options to STAmount and STNumber
ctors, conversions, etc. IOUs are never checked.
- Update Vault transactors, and helper functions, to check restrictions.
- Fix and add Vault tests.
- Scale the loan to the Vault, so that amounts moving to the vault are
less likely to have rounding errors.
- Similar to LoanPay, when LoanManage defaults a loan, round the amounts
to the Vault scale (because the Vault scale can change) before
applying them to the Vault.
