Galaktos seems to use %f
%f printf() specifier gives inconsistent result depending on the user's locale. We cannot assume it will be the american format either (as per #581 (closed)). You cannot use strof() either.
Don't use it when read from/writing to a file or a network stream.
modules/visualization/galaktos/init_cond.c: sprintf(string, "%s=%f\n", init_cond->param->name, init_cond->init_val.double_val);
