You could use XOR 0 to force the integer part.

With positive small values this is the same as Math.floor(),
but probably[!] faster.

return [
      'N','NNE',
      'NE','ENE','E','ESE',
      'SE','SSE','S','SSW',
      'SW','WSW','W','WNW',
      'NW','NNW'
    ][ (this.deg + 11.25) / 22.5 % 16 ^ 0 ];
