an engine that has floating point (double) numbers implemented
This engine type plays nice with the IntEngine functions by supplemening its operators to be able to mix float and int in operations.
Per default only the float versions are pre-installed. Use IntEngine::configureIntEngine or IntFloatEngine to have both.
