What is the proper data annotation to format my decimal property?

问题

I have a POCO with a decimal property called SizeUS. I would like to use data annotations to format the display of the decimal in a view. My SizeUS property is only displaying 2 decimal places in my view and I want it to display 4 decimal places. What is the proper data annotation to accomplish this ?

[DisplayFormat( ? )]
public decimal SizeUS {get; set;}

[DisplayFormat(DataFormatString="{0:#.####}")]

See Custom Format Strings for formats and DisplayFormatAttribute for examples
