`Exact_rational` is an exact rational number type, constructible from `double`.
|
||
|
|
|
||
|
|
It is a typedef of another number type. Its exact definition depends on
|
||
|
|
the availability the third-party libraries %GMP, %CORE, and %LEDA. %CGAL must
|
||
|
|
be configured with at least one of those libraries.
