8e56af20ee Add a distinction between a "valid" and a "representable" 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.

0175dd70db Catch up the consequences of Number changes
- 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.

1d42c4f6de refactor: Remove unnecessary copyright notices already covered by LICENSE.md (#5929)
Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).

This change specifically removes all copyright notices referencing Ripple, XRPLF, and certain affiliated contributors upon mutual agreement, so the notice in the LICENSE.md file applies throughout. Copyright notices referencing external contributions remain as-is. Duplicate verbiage is also removed.

fb8dafa6a8 Refactor Number, add tests, update LoanManage, update LoanPay
- Loan tests are not expected to pass.
- Refactor Number to put rounding logic into reusable functions.
- Add Number tests to explicitly test rounding - may be redundant, but
  easy to reason about.  Verifies that the default rounding matches
  banker's rounding.
- Enable LoanManage. Apparently any remaining issues were fixed by the
  previous commit's cleanups.
- Partially enabled LoanPay.

cf5f65b68e Add Scale to SingleAssetVault (#5652)
* Add and Scale to VaultCreate
* Add round-trip calculation to VaultDeposit VaultWithdraw and VaultClawback
* Implement Number::truncate() for VaultClawback
* Add rounding to DepositWithdraw
* Disallow zero shares withdraw or deposit with tecPRECISION_LOSS
* Return tecPATH_DRY on overflow when converting shares/assets
* Remove empty shares MPToken in clawback or withdraw (except for vault owner)
* Implicitly create shares MPToken for vault owner in VaultCreate
* Review feedback: defensive checks in shares/assets calculations

b7ed99426b fix: Make test suite names match the directory name (#5597)
This change fixes the suite names all around the test files, to make them match to the folder name in which this test files are located. Also, the RCL test files are relocated to the consensus folder, because they are testing consensus functionality.

2406b28e64 refactor: Remove unused and add missing includes (#5293)
The codebase is filled with includes that are unused, and which thus can be removed. At the same time, the files often do not include all headers that contain the definitions used in those files. This change uses clang-format and clang-tidy to clean up the includes, with minor manual intervention to ensure the code compiles on all platforms.

ea1fffeebf Enforce levelization in libxrpl with CMake (#5111)
Adds two CMake functions:

* add_module(library subdirectory): Declares an OBJECT "library" (a CMake abstraction for a collection of object files) with sources from the given subdirectory of the given library, representing a module. Isolates the module's headers by creating a subdirectory in the build directory, e.g. .build/tmp123, that contains just a symlink, e.g. .build/tmp123/basics, to the module's header directory, e.g. include/xrpl/basics, in the source directory, and putting .build/tmp123 (but not include/xrpl) on the include path of the module sources. This prevents the module sources from including headers not explicitly linked to the module in CMake with target_link_libraries.
* target_link_modules(library scope modules...): Links the library target to each of the module targets, and removes their sources from its source list (so they are not compiled and linked twice).

Uses these functions to separate and explicitly link modules in libxrpl:

    Level 01: beast
    Level 02: basics
    Level 03: json, crypto
    Level 04: protocol
    Level 05: resource, server

e354497f63 Include rounding mode in XRPAmount to STAmount conversion. 2023-02-07 15:43:28 -08:00

3f33471220 Introduce rounding modes for Number:
You can set a thread-local flag to direct Number how to round
non-exact results with the syntax:

    Number::rounding_mode prev_mode = Number::setround(Number::towards_zero);

This flag will stay in effect for this thread only until another call
to setround.  The previously set rounding mode is returned.

You can also retrieve the current rounding mode with:

    Number::rounding_mode current_mode = Number::getround();

The available rounding modes are:

* to_nearest : Rounds to nearest representable value.  On tie, rounds
               to even.
* towards_zero : Rounds towards zero.
* downward : Rounds towards negative infinity.
* upward : Rounds towards positive infinity.

The default rounding mode is to_nearest.
