   Hey #schemers !
   I have two numbers in strings with comma as decimal separator (e.g. "0,46" and "0,098")

   Any idea how I can get their sum in simpler way than this :
   (use-modules (ice-9 string-fun))
   (+ (string->number (string-replace-substring "0,24" "," ".")) (string->number (string-replace-substring "0,098" "," ".")))

   Feels heavy…

   Thx!

     @jeko I don't think there's another simple way. In other languages you can use the locales for that, but I don't think it's the case in Scheme.

     @jeko Of course this is something impossible to find a search engine so... that's why I don't use guile/scheme that much... too many problems that I can't find a solution about.

     @jeko Try ‘locale-string->inexact’ from (ice-9 i18n) in a French locale:

     (locale-string->inexact "3,14" (make-locale LC_ALL "fr_FR.utf8"))
     ⇒ 3.14

     @civodul @jeko Oh my god. It's here:

     Impossible to find... :S

     @ekaitz_zarraga @jeko You’re looking at the 2.0 manual; this API hasn’t changed, but check out:

     @civodul @jeko AGAIN: Impossible to find it properly AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

     @ekaitz_zarraga @jeko Re “impossible to find”, there’s a function index, accessible by typing ‘i’ in an Info reader, and on-line at https://www.gnu.org/software/guile/manual/html_node/Procedure-Index.html

     Ideas on how to improve on that are much welcome!

     @civodul @jeko that's useful to find a function you know but you don't know what it does, but it's not useful to learn how to do something.
     Get what I mean?

     @ekaitz_zarraga @jeko Then again, I’m an old fart, which is why I’m used to searching for info in manuals rather than in a search engine. :-)

     (Searching for Guile stuff in a search engine is never going to work as efficiently for Guile as it does for JavaScript or C++ anyway…)

     @civodul @jeko yeah... I guess I have to learn to use the info pages better...
