- Method Detail
  - getLB
```
double getLB()
```
    Retrieves the lower bound of the variable
    
    Returns:
    
    the lower bound
  - getUB
```
double getUB()
```
    Retrieves the upper bound of the variable
    
    Returns:
    
    the upper bound
  - intersect
```
default void intersect(RealInterval interval,
                       ICause cause)
                throws ContradictionException
```
    Modifies the bounds for intersecting with the specified interval.
    
    Parameters:
    
    interval - an interval
    
    cause - who launches the intersection
    
    Throws:
    
    ContradictionException - if a failure occurs
  - intersect
```
void intersect(double l,
               double u,
               ICause cause)

    Modifies the bounds for intersecting with the specified interval.
    
    Parameters:
    
    l - lower bound
    
    u - upper bound
    
    cause - who launches the intersection
    
    Throws:
