T5.0.6 : How to format a number in a TextField

In Tap 4, I can use translator:number,pattern=0.#
(which used NumberTranslator.java)
to format the numeric value  in a TextField component.

How can this be done in T5.0.6 ? 

I have checked the  T5.0.6 API, it looks as though
T5.0.6 has no
NumberTranslator.java .

Must I implement a NumberTranslator ?

I have extended DoubleTranslator.java and 
override the method DoubleTranslator.toClient to
format the output.


public class MyDoubleTranslator extends
DoubleTranslator{

	@Override
	public String toClient(Double value) {
		String returnValue = null;
		
		DecimalFormat formatter = new DecimalFormat("0.#");
		if (value==null){
			returnValue = "";
		}
		else{
			returnValue = formatter.format(value);
		}
		return returnValue;
	}
	
}

In AppModule, I added 

 public static void contributeTranslatorSource(
            MappedConfiguration<String, Translator>
configuration)
    {
      
        configuration.add("myDouble", new
MyDoubleTranslator());
    }

Now I just add  translate="translate:myDouble"
to <t:textField> to have the displayed number
formatted . The above works. But the format pattern
"#.0" is 
hard coded.  

Is there anyway to do something like 
 translate="translate:myDouble,pattern=#.0" ?

Thanks in advance for any assistance!
