[Bug 1589717] Re: bc cannot handle "comma" instead of "dot" in floating point operations

[benjamin button]

I believe decimal separator symbol varies from region to region, so is
there any way to get the correct decimal separator?

I can now clearly see that this bug is valid if "bc" cannot get (or
convert) the correct decimal separator. Is there any other bug(s) that
prevents bc to get the correct symbol? Because user selects the region
and country information at the installing screen on most distros. Hence
the system should know which decimal point separator will be used as
default.

I don't see any necessity to support different decimal separator
symbols. If there is no counter-argument, I would like to mark this bug
as "WON'T FIX".
