In this case it may hurt that floating point math is done in software as the CPU in real device has only single precision floats and javascript uses doubles. Basic set would work just fine with single precision floats. I made some experiments with it and it is doable even with no changes in espruino, see http://forum.espruino.com/conversations/337810/ This of course does not make sense with emulator now, only with real device.
