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

If you arrived here and are only interested in breaking your degrees into one of 8 directions.

function degToCompass(num){
    const val =  Math.floor((num / 45) + 0.5);
    const arr = ["N","NE","E", "SE","S","SW","W","NW"];
    return arr[(val % 8)]
