51 | // The numeric_limits<> traits document implementation-defined aspects | |
52 | // of fundamental arithmetic data types (integers and floating points). | |

55 | // bool (1) | |
56 | // char, signed char, unsigned char (3) | |
57 | // short, unsigned short (2) | |
58 | // int, unsigned (2) | |
