Private Attributes | |
T | m_value |
The non-overflow safe backend to store the value in. |
Overflow safe template for integers, i.e.
integers that will never overflow you multiply the maximum value with 2, or add 2, or subtract something from the minimum value, etc.
T | the type these integers are stored with. |
T_MAX | the maximum value for the integers. |
T_MIN | the minimum value for the integers. |
