DATARANGE serialization type invalid [MAPSCRIPT] #4992

I have detected a serialization problem with the DATARANGE fields when using the Mapscript methods mapfile.convertToString () and () causing information loss. Indeed, the DATARANGE (type double) are serialized as integer.

This seems to happen in the file mapfile.c :
In the writeStyle function, the DATARANGE is serialized with the writeDimension function which use msIO_fprintf(stream, "%s %d ", name, x); (note : remark the %d).
Another write* function must be created to handle a couple of double values.

For ex. (not tested yet):

static void writeDataRange(FILE *stream, int indent, const char *name, double x, double y)
  writeIndent(stream, ++indent);
  msIO_fprintf(stream, "%s %f.4 %f.4\n", name, x, y);

Correct me and reopen the ticket if I am wrong, but if the patch is merged and comment says that it corrects issue #4992, isn't this issue fixed then?
