```
public class KFloatVar
extends KNumVar
```
This class implements a variable with continuous real valued domain.
Conceptually the continuous variables can be represented the following way :

Example:
```
KProblem  p(...);

 // X is a continuous variable that can take real value between interval [0..10]
	KFloatVar X(p,"X",0,10);
```

2016.1
