  - GroupJep
```
public GroupJep(GroupI group)
```
    Create a new GroupJep instance with calculations over the given group.
    
    Parameters:
    
    group - The group to calculate over.
  - GroupJep
```
public GroupJep(JEP j)
```
- Method Detail
  - addStandardFunctions
```
public void addStandardFunctions()
```
    Description copied from class: JEP
    
    Adds the standard functions to the parser. If this function is not called before parsing an expression, functions such as sin() or cos() would produce an "Unrecognized function..." error. In most cases, this method should be called immediately after the JEP object is created.
    
    Overrides:
    
    addStandardFunctions in class JEP
  - addStandardConstants
```
public void addStandardConstants()
```
    Description copied from class: JEP
    
    Adds the constants pi and e to the parser. As addStandardFunctions(), this method should be called immediately after the JEP object is created.
    
    Overrides:
    
    addStandardConstants in class JEP
  - getGroup
```
public GroupI getGroup()
```
  - getComplexValue
```
public Complex getComplexValue()
```
    Calcuates the value of the expression and returns the result as a complex number.
    
    Overrides:
    
    getComplexValue in class JEP
    
    Returns:
    
    The calculated value of the expression as a complex number if no errors occur. Returns null otherwise.
  - complexValueOf
```
public static Complex complexValueOf(Object num)
```
    A utility function which returns the complex aproximation of a number.
    
    Parameters:
    
    num - the object to be converted
    
    Returns:
    
    the complex aproximation or null if conversion to complex is not posible.
