Except when you shouldn't ... If you are getting arguments that are locale dependent changing the locale will do you more harm than good, so now you need to parse arguments before changing locale, assuming you know what the locale of the arguments is and how to translate them to the C locale. System commands should probably not change their syntax based on locale. Ping can very well document that the -i argument takes an interval using C locale and not do locale dependent parsing. It would be much more robust and if you are good enough to use the -i switch you probably know how to type 0.1 instead of 0,1 (or whatever format is in your locale) as well.
