You need to set the DecimalSeparator character (to ',' in your case) , 
and format  your floats with floattostr or one of the other formatting 
routines in sysutils.

The system unit routines always use '.' as a decimal separator. If you don't
want to use the sysutils routines, use Str() to convert to a string, and replace
the dot with a comma in the resulting string.
