@miri64 Thanks for merging :smile: 

> Test succeeds now. I'm not sure if the float output is correct (I doubt all of the test ran in less than 500μs) but at least this removes this is a step in removing this pesky red badge on the main GitHub page ;-).

The float output seems to works. I have tested it with `printf("%.3f\n", 0.123)` which gives the correct output.

Concerning the runtime of the tests, I was already wondering why all runtimes are `0.000`, although at least some of the tests produce a noticeable delay. But this was the same before and is not related to the `printf` function.
