template<typename T1, typename T2 = T1>
class theoretica::ratio< T1, T2 >
representing a ratio between two objects, like a fraction or a rational polynomial.
- Note
- For the class to properly work, the template types need to have operator*, operator+ and operator- defined.
◆ ratio()
template<typename T1 , typename T2 = T1>
Construct the object from two objects.
- Parameters
-
| n | The numerator |
| d | The denominator |
◆ eval_as()
template<typename T1 , typename T2 = T1>
template<typename T >
Evaluate the ratio as the division between numerator and denominator cast to the specified type.
This function is well-defined only if division between objects of type T is defined. A static cast is performed before division.
◆ operator T2()
template<typename T1 , typename T2 = T1>
Evaluate the ratio as the division between numerator and denominator cast to the type of the denominator.
