Detailed Description

Declaration of the ns3::int64x64_t type using a native int128_t type.

Macro Definition Documentation

HP_MAX_64

#define HP_MAX_64   (std::pow (2.0L, 64))

Floating point value of HP_MASK_LO + 1.

We really want:

static const long double HP_MAX_64 = std:pow (2.0L, 64);

but we can't call functions in const definitions.

We could make this a static and initialize in int64x64-128.cc or int64x64.cc, but this requires handling static initialization order when most of the implementation is inline. Instead, we resort to this define.
