// 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 13 such types:
|
|
// * integers
|
|
// bool (1)
|
|
// char, signed char, unsigned char (3)
|
|
// short, unsigned short (2)
|
|
// int, unsigned (2)
|
|
// long, unsigned long (2)
|

|

// * floating points
|
|
// float (1)
|
|
// double (1)
|
|
// long double (1)
|

//
|
|
// GNU C++ undertstands (where supported by the host C-library)
|
|
// * integer
|
|
// long long, unsigned long long (2)
|
|
//
|
|
// which brings us to 15 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.
