[Fwd: german locale Problem]

[Hans-Bernhard B. <br...@ph...>]

Hello, guys,

I received mail from a German user of gnuplot on Win32 who observes 
strange behaviour, apparently from 'set decimalsign locale' being set to 
German:

Version:
         G N U P L O T
         Version 4.2 patchlevel 2
         last modified 31 Aug 2007
         System: MS-Windows 32 bit

[Condensed] script to reproduce:

set datafile separator ';'
set decimalsign locale 'german'
p1              = -22.5
p2              = 52.5
p3              = 30
p(x)=p1*(x-2001)**2+p2*(x-2001)+p3
print p(2005)
print p(2005.5)

Output from the two print commands is:

-120.0
-189,375

Note that it's -120.0, with a '.', instead of the requested and expected 
',', while the output of -189,375 worked as expected.  Does this ring a 
bell with anyone?

I would have checked it against current CVS gnuplot, but the version 
built by OpenWatcom doesn't appear to know any German locales --- 
they're all rejected:

gnuplot> set decimalsign locale 'german'
                                 ^
          Could not find requested locale
