- Simplify Number::operator/= to use more constexpr values, and fewer
variations.
- Most significantly, rounding up doesn't need more precision, it only
needs to know if there's a remainder after the current precision work
is done. Tracked similarly Guard::xbit_.
- Build a constexpr lookup array for powers of 10. Only a handful of
values are used, but since it's built at compile time, and constexpr,
unused values do not affect memory or performance.
- Order the checks so that large mantissa is only enabled if SAV or LP
are enabled. fixCleanup3_2_0 only enables the rounding fix.
- Fix tests, and don't exclude fixCleanup3_2_0 in AMM tests
- Also fix formatting
* XRPLF/develop:
release: Set version to 3.3.0-b0 (7280)
refactor: Rename static constants (7120)
refactor: Use `isFlag` where possible instead of bitwise math (7278)
ci: Update XRPLF/actions (7281)
- Refactor the Guard decision in withTxnType into createGuards, which
lives in Rules.cpp. It is physically located near
setCurrentTransactionRules, and documented to explain that changes
need to be synchronized.
- Add helper function, doDropDigit, to wrap the common pattern:
push(mantissa % 10);
mantissa /= 10;
++exponent;
- Might have been helpful to catch this issue when developing.
Throwing exceptions from code sometime confuses ASAN, as it cannot keep track of stack frames. This change therefore adds a macro to skip instrumentation around the `Throw` function.
Unity builds were intended to speed up builds, by bundling multiple files into compilation units. However, now that ccache is available on all platforms, there is no need for unity builds anymore, as ccache stores compiled individual build objects for reuse. This change therefore removes the ability to make unity builds.
The `Number.h` header file now has `std::reference_wrapper` from `<functional>`, but the include is missing, causing downstream build problems. This change adds the header.
- Refactor Number internals away from int64 to uint64 & a sign flag
- ctors and accessors use `rep`. Very few things expose
`internalrep`.
- An exception is "unchecked" and the new "normalized", which explicitly
take an internalrep. But with those special control flags, it's easier
to distinguish and control when they are used.
- For now, skip the larger mantissas in AMM transactions and tests
- Remove trailing zeros from scientific notation Number strings
- Update tests. This has the happy side effect of making some of the string
representations _more_ consistent between the small and large
mantissa ranges.
- Add semi-automatic rounding of STNumbers based on Asset types
- Create a new SField metadata enum, sMD_NeedsAsset, which indicates
the field should be associated with an Asset so it can be rounded.
- Add a new STTakesAsset intermediate class to handle the Asset
association to a derived ST class. Currently only used in STNumber,
but could be used by other types in the future.
- Add "associateAsset" which takes an SLE and an Asset, finds the
sMD_NeedsAsset fields, and associates the Asset to them. In the case
of STNumber, that both stores the Asset, and rounds the value
immediately.
- Transactors only need to add a call to associateAsset _after_ all of
the STNumbers have been set. Unfortunately, the inner workings of
STObject do not do the association correctly with uninitialized
fields.
- When serializing an STNumber that has an Asset, round it before
serializing.
- Add an override of roundToAsset, which rounds a Number value in place
to an Asset, but without any additional scale.
- Update and fix a bunch of Loan-related tests to accommodate the
expanded Number class.
