Error in http://arduino.cc/en/Reference/RobotPlayMelody

I think that the description on the page http://arduino.cc/en/Reference/RobotPlayMelody of the modifier '.' is incorrect. Where it describes note durations, it says ". : Make the previous note 3/4 its length". Comparing this to the source at https://github.com/arduino/Arduino/blob/master/libraries/Robot_Control/Melody.cpp, this should be 2/3, not 3/4.

Thanks for the notice, I've moved it on the issue tracker on GitHub to involve documentation maintainers:
