// The numeric_limits<> traits document implementation-defined aspects |
| 46 |
// of fundamental arithmetic data types (integers and floating points). |
| 47 |
// From Standard C++ point of view, there are 14 such types: |
| 48 |
// * integers |
| 49 |
// bool (1) |
| 50 |
// char, signed char, unsigned char, wchar_t (4) |
| 51 |
// short, unsigned short (2) |
| 52 |
// int, unsigned (2) |
| 53 |
// long, unsigned long (2) |
| 54 |
// |
| 55 |
// * floating points |
| 56 |
// float (1) |
| 57 |
// double (1) |
| 58 |
// long double (1) |
| 59 |
// |
| 60 |
// GNU C++ understands (where supported by the host C-library) |
| 61 |
// * integer |
| 62 |
// long long, unsigned long long (2) |
| 63 |
// |
| 64 |
// which brings us to 16 fundamental arithmetic data types in GNU C++. |
| 65 |
// |
| 66 |
// |
| 67 |
// Since a numeric_limits<> is a bit tricky to get right, we rely on |
| 68 |
// an interface composed of macros which should be defined in config/os |
| 69 |
// or config/cpu when they differ from the generic (read arbitrary) |

// definitions given here. |
