-// uint128
-//
-// An unsigned 128-bit integer type. The API is meant to mimic an intrinsic type
-// as closely as is practical, including exhibiting undefined behavior in
-// analogous cases (e.g. division by zero). This type is intended to be a
-// drop-in replacement once C++ supports an intrinsic `uint128_t` type; when
-// that occurs, existing well-behaved uses of `uint128` will continue to work
-// using that new type.
-//
-// Note: code written with this type will continue to compile once `uint128_t`
-// is introduced, provided the replacement helper functions
-// `Uint128(Low|High)64()` and `MakeUint128()` are made.
-//
-// A `uint128` supports the following:
-//
-//   * Implicit construction from integral types
-//   * Explicit conversion to integral types
-//
-// Additionally, if your compiler supports `__int128`, `uint128` is
-// interoperable with that type. (Abseil checks for this compatibility through
-// the `ABSL_HAVE_INTRINSIC_INT128` macro.)
-//
-// However, a `uint128` differs from intrinsic integral types in the following
-// ways:
-//
-//   * Errors on implicit conversions that do not preserve value (such as
-//     loss of precision when converting to float values).
-//   * Requires explicit construction from and conversion to floating point
-//     types.
-//   * Conversion to integral types requires an explicit static_cast() to
-//     mimic use of the `-Wnarrowing` compiler flag.
-//   * The alignment requirement of `uint128` may differ from that of an
-//     intrinsic 128-bit integer type depending on platform and build
-//     configuration.
-//
-// Example:
-//
-//     float y = absl::Uint128Max();  // Error. uint128 cannot be implicitly
-//                                    // converted to float.
-//
-//     absl::uint128 v;
-//     uint64_t i = v;                         // Error
-//     uint64_t i = static_cast<uint64_t>(v);  // OK
