RationalBigInt

java.lang.Object
- de.uni_kl.cs.discodnc.numbers.implementations.RationalBigInt

All Implemented Interfaces:

Num
```
public class RationalBigInt
extends java.lang.Object
implements Num
```
Wrapper class around org.apache.commons.math3.BigFraction.BigFraction introducing special values like positive / negative infinity and NaN as well as operators like min, max, ==, >, >=, <, and <= that are not part of BigFraction but needed by the network calculator.
For the ease of converting from the primitive data type double to BigFraction objects, copy by value semantic are is applied.
