[GNC] Decimal separator on Gnucash 3.2 Mac

[Yves Forget]

   I’m new to GnuCash and just installed GnuCash 3.2 on Mac. OS X 10.13
   Gnucash uses the period as decimal separator instead of my locale’s
   separator.  Here in Canada it should be comma.
   Should Gnucash use the decimal separator of my locale, or is it always
   period ?  Is there a way to configure it within GnuCash ?
   Thanks,
