Rick is right I guess, see result from "LC_NUMERIC=C rexx osmmap.rex"
-------------------------------------------------------------------------------
ruurd@Paradigit2:~/newrxgtk/GTKv3/test$ LC_NUMERIC=C rexx osmmap.rex
As CSTRINGs - Latitude: 52.289875;Longitude: 4.8448525
As objects - Latitude: 52.289875;Longitude: 4.8448525
As doubles - Latitude: 52.289875; Longitude: 4.844853

As an aside for Erich, I started with the arguments as float and the
result triggered the trial bypass via CSTRING.

Hi Ruurd, instead of defining your latitude/longitude arguments as
CSTRING and then manually converting them, you can define your
arguments as (e. g.) float and have Rexx do the conversion for you.

float lat, // Latitude in decimal degrees
float lon, // Longitude in decimal degrees

The actual issue may be a bug as ObjectToDouble calls C's strtod()
which seems to adhere to the locale (decimal dot vs decimal comma).
It seems rexx doesn't globally set the "C" locale but runs with
whatever locale it is being started in.
I suspect that is the case. The actual work is done in method
NumberString::doubleValue(), which uses strtod() to do the conversion.
Since the numberstring object already has already parsed off the
matissa, exponent, and sign, it should not be difficult to directly
generate a double value from that information.

Does it work as expected if you run your script in either of these
two forms?
LANG=C rexx <name.rex>
LC_NUMERIC=C rexx <name.rex>
