Detailed Description

This class contains labels for probabilistic transistions, consisting of a numerator and a denumerator.

This class provides a number of operators to calculate with real constants (actually fractions). Comparisons of more complex expressions may not always rewrite properly. There are methods to add and subtract such labels. The numbers are used as 64 bit integers. If the integers do not fit into 64 bit, the numerator and denumerator are adapted to make them fit. This means that this library is not exact, but employs rounding at times.
