#include <tvmet/NumericTraits.h>

List of all members.

Detailed Description

template<class T>
class tvmet::NumericTraits< T >

Traits for integral types for operations.

For each type we have to specialize this traits.

Note:
Keep in mind that the long types long long and long double doesn't have traits. This is due to the sum_type. We can't give a guarantee that there is a type of holding the sum. Therefore using this traits is only safe if you have long long resp. long double types by working on long ints and doubles. Otherwise you will get not expected result for some circumstances. Anyway, you can use big integer/float libraries and specialize the traits by your own.
Todo:
The abs function of complex<non_float_type> can have an overrun due to numeric computation. Solve it (someone using value_type=long here?)
