  Fix crash in index sample code

The example on dlang.org's index page which rounds floats currently crashes when ran. If you dump out `args` you can see that for some reason it's getting an empty string as `arg[1]`: `["./f347", ""]`

To "fix" this, I just removed support for reading from args.

```
