  - convertToModel
```
public Double convertToModel(String value,
                             Class<? extends Double> targetType,
                             Locale locale)
                      throws Converter.ConversionException
```
    Description copied from interface: Converter
    
    Converts the given value from target type to source type.
    A converter can optionally use locale to do the conversion.
    A converter should in most cases be symmetric so chaining Converter.convertToPresentation(Object, Class, Locale) and Converter.convertToModel(Object, Class, Locale) should return the original value.
    
    Parameters:
    
    value - The value to convert, compatible with the target type. Can be null
    
    targetType - The requested type of the return value
    
    locale - The locale to use for conversion. Can be null.
    
    Returns:
    
    The converted value compatible with the source type
    
    Throws:
    
    Converter.ConversionException - If the value could not be converted
  - getModelType
```
public Class<Double> getModelType()
```
    Description copied from interface: Converter
    
    The source type of the converter. Values of this type can be passed to Converter.convertToPresentation(Object, Class, Locale).
    
    Returns:
    
    The source type
