Thread:Support/Magic Word R

Hello. There is ongoing discussion at w:hi:विकिपीडिया:चौपाल/जादुई शब्द अनुवाद for magic word translation.

The AdvancedTranslate page contains a magic word R. mw:Help:Magic words shows me that R has various uses in various magic words, such as:
 * or or  gives raw numbers
 * 987,654,321.654 reverses the usual behaviour of formatnum.

Which of these uses does the R in advancedTranslate refer to?

Thanks for the help.
