It is in the documentation:

http://freemarker.org/docs/pgui_config_settings.html

http://freemarker.org/docs/app_faq.html#faq_number_grouping (linked in the Built-ins for numbers page)

Simple code:

Environment env = myTemplate.createProcessingEnvironment(root, out);
env.setNumberFormat(env.getCNumberFormat());
env.process();
