//
// The numeric_limits<> traits document implementation-defined aspects
// of fundamental arithmetic data types (integers and floating points).
// From Standard C++ point of view, there are 14 such types:
// * integers
// bool (1)
// char, signed char, unsigned char, wchar_t (4)
// short, unsigned short (2)
// int, unsigned (2)
// long, unsigned long (2)
//
// * floating points
// float (1)
// double (1)
// long double (1)
//
// GNU C++ understands (where supported by the host C-library)
// * integer
// long long, unsigned long long (2)
//
// which brings us to 16 fundamental arithmetic data types in GNU C++.
//
//
// Since a numeric_limits<> is a bit tricky to get right, we rely on
// an interface composed of macros which should be defined in config/os
// or config/cpu when they differ from the generic (read arbitrary)
// definitions given here.
//
// These values can be overridden in the target configuration file.
// The default values are appropriate for many 32-bit targets.
// GCC only intrinsically supports modulo integral types. The only remaining
// integral exceptional values is division by zero. Only targets that do not
// signal division by zero in some "hard to ignore" way should use false.
