You'd think so, but read these stunning strtod() algorithm descriptions (a
must-read for anyone who likes math).

Rick is right I guess, see result from "LC_NUMERIC=C rexx osmmap.rex"

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
I guess I found the cause. It's the decimal point vs the decimal comma
(for my locale) that is causing the behaviour.
If I set the latitude and longitude in an ENVIRONMENT variable via VALUE
and retrieve those with GObject "g_getenv" function, then all goes well
if I use the comma as decimal
In the real code the tildes in the printf as objects are "->". Made a
mistake when I type the code manually.
