I'm trying to print out Double in russian locale (we use "," as decimal separator insetad of "."). I'm trying to set locale with System.Locale.SetLocale like
setLocale LC_ALL $ Just "ru_RU.UTF-8"
this returns Just "ru_RU.UTF-8", so it seems that function call succeeded, but when I call
show 20.2
it just prints 20.2 and not desired 20,2
Can anyone please help?
By design, show and read don't use the locale. Not to mention that since Haskell is pure, it is *impossible* for the expression show 20.2 :: String to depend on the current locale. I have never tried to use locales in Haskell, maybe someone else can help. Most likely, you'll need to do foreign imports of C functions. Regards, apfelmus -- http://apfelmus.nfshost.com
