The point of this class is to be a number of type T which is known at compile time to be zero.
This is reflected in the operations like addition and subtraction that use it. If you return a Zero object, the compiler should be able to make better optimizations than if you just return zero.
Zero is templated on type T, to represent a zero object of type T. Type T is required to be constructable from an integer zero.
Give it empty ctors and assignment operators to try and keep purify happy.
Zero< T >::operator T | ( | ) | const [inline] |
If you need to convert to an object of type T, just build one from zero.
This will be used in the cases where the operators below don't match.
