Converting wind direction in angles to text words

Question

I have wind direction data coming from a weather vane, and the data is represented in 0 to 359 degrees.

I want to convert this into text format (compass rose) with 16 di

Answer 1

I believe it is easier to:

1. Shift the direction by 11.25
2. Add an "N" at the end of the direction list to handle the 'over 360',

DirTable = ["N","NNE","NE","ENE","E","ESE", "SE","SSE","S","SSW","SW","WSW", "W","WNW","NW","NNW",**"N"**]; 

wind_direction= DirTable[Math.floor((d+11.25)/22.5)];
