- * STNumber field type, and for internal calculations. That necessitated the

- *
- * It can represent all values that can be represented by an STAmount -
- * regardless of asset type - XRPAmount, MPTAmount, and IOUAmount, with at least
- * as much precision as those types require.
- *
- * ---- Internal Representation ----
- *
- * Internally, Number is represented with three values:
- *   1. a bool sign flag,
- *   2. a std::uint64_t mantissa,
- *   3. an int exponent.
- *
- * The internal mantissa is an unsigned integer in the range defined by the
- * current MantissaRange. The exponent is an integer in the range
- * [minExponent, maxExponent].
- *
- * See the description of MantissaRange for more details on the ranges.
- *
- * A non-zero mantissa is (almost) always normalized, meaning it and the
- * exponent are grown or shrunk until the mantissa is in the range
- * [MantissaRange.min, MantissaRange.max].
- *
- * Note:
- *   1. Normalization can be disabled by using the "unchecked" ctor tag. This
- *      should only be used at specific conversion points, some constexpr
- *      values, and in unit tests.
- *   2. The max of the "large" range, 10^19-1, is the largest 10^X-1 value that
- *      fits in an unsigned 64-bit number. (10^19-1 < 2^64-1 and
- *      10^20-1 > 2^64-1). This avoids under- and overflows.
- *
- * ---- External Interface ----
- *
- * The external interface of Number consists of a std::int64_t mantissa, which
- * is restricted to 63-bits, and an int exponent, which must be in the range
- * [minExponent, maxExponent]. The range of the mantissa depends on which
- * MantissaRange is currently active. For the "short" range, the mantissa will
- * be between 10^15 and 10^16-1. For the "large" range, the mantissa will be
- * between -(2^63-1) and 2^63-1. As noted above, the "large" range is needed to
- * represent the full range of valid XRP and MPT integer values accurately.
- *
- * Note:
- *   1. 2^63-1 is between 10^18 and 10^19-1, which are the limits of the "large"
- *      mantissa range.
- *   2. The functions mantissa() and exponent() return the external view of the
- *      Number value, specifically using a signed 63-bit mantissa. This may
- *      require altering the internal representation to fit into that range
- *      before the value is returned. The interface guarantees consistency of
- *      the two values.
- *   3. Number cannot represent -2^63 (std::numeric_limits<std::int64_t>::min())
- *      as an exact integer, but it doesn't need to, because all asset values
- *      on-ledger are non-negative. This is due to implementation details of
- *      several operations which use unsigned arithmetic internally. This is
- *      sufficient to represent all valid XRP values (where the absolute value
- *      can not exceed INITIAL_XRP: 10^17), and MPT values (where the absolute
- *      value can not exceed maxMPTokenAmount: 2^63-1).
- *
- * ---- Mantissa Range Switching ----
- *
- * The mantissa range may be changed at runtime via setMantissaScale(). The
- * default mantissa range is "large". The range is updated whenever transaction
- * processing begins, based on whether SingleAssetVault or LendingProtocol are
- * enabled. If either is enabled, the mantissa range is set to "large". If not,
- * it is set to "small", preserving backward compatibility and correct
- * "amendment-gating".
- *
- * It is extremely unlikely that any more calls to setMantissaScale() will be
- * needed outside of unit tests.
- *
- * ---- Usage With Different Ranges ----
- *
- * Outside of unit tests, and existing checks, code that uses Number should not
- * know or care which mantissa range is active.
- *
- * The results of computations using Numbers with a small mantissa may differ
- * from computations using Numbers with a large mantissa, specifically as it
- * effects the results after rounding. That is why the large mantissa range is
- * amendment gated in transaction processing.
- *
- * It is extremely unlikely that any more calls to getMantissaScale() will be
- * needed outside of unit tests.
- *
- * Code that uses Number should not assume or check anything about the
- * mantissa() or exponent() except that they fit into the "large" range
- * specified in the "External Interface" section.
- *
- * ----- Unit Tests -----
- *
- * Within unit tests, it may be useful to explicitly switch between the two
- * ranges, or to check which range is active when checking the results of
- * computations. If the test is doing the math directly, the
- * set/getMantissaScale() functions may be most appropriate. However, if the
- * test has anything to do with transaction processing, it should enable or
- * disable the amendments that control the mantissa range choice
- * (SingleAssetVault and LendingProtocol), and/or check if either of those
- * amendments are enabled to determine which result to expect.
