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);
#define HP_MAX_64
Floating point value of HP_MASK_LO + 1 We really want:
STL namespace.

but we can't call functions in const definitions, We could make this a static and initialize in int64x64-cairo.cc or int64x64.cc, but this requires handling static initialization order when most of the implementation is inline. Instead, we resort to this define.

◆ INT64X64_CAIRO_H

#define INT64X64_CAIRO_H
