Out of curiosity, why?

Otherwise I don't think it's possible in FreeMarker, since it's number
formatting is what the Java platform provides, and DecimalFormat uses
half-even rounding, and it isn't configurable in this regard. That
said, you couldn't even do that in a Java program. So, blame the J2SE
API guys... ;)

Of course, you could write the function for this easily:

<#function n3 n>
  <#return ((n*1000)?round/1000)?string>
</#function>
