```
- Method Detail
  - re
```
public RealNum re()
```
    Description copied from class: Quantity
    
    The value of the real component, as a RealNum. The unit() is not factored in, so you actually need to multiply by unit() to get the true real component.
    
    Overrides:
    
    re in class Quantity
  - doubleValue
```
public double doubleValue()
```
    Description copied from class: Quantity
    
    The value of the real component, as a double. This is relative to the unit().dims - i.e. unit()/doubleValue() is factored in.
    
    Overrides:
    
    doubleValue in class Complex
