please use `StringUtils::toDouble()` instead of `atof`. Chris has spent quite a bit of time evaluating the different options and found one that works best on all platforms, so it is nice to have the same code everywhere for parsing strings to numbers. Not sure whether this is performance critical, but still doing it at one place allows for easy change.
