Math.degrees = function (rad) {
const degrees = (rad * 180) / Math.PI
const rounded = Math.round(degrees * 100) / 100
return `${rounded}deg`
}

Math.radians = function (deg) {
const radians = (deg * Math.PI) / 180
const rounded = Math.round(radians * 100) / 100
return `${rounded}rad`
}

// Math.degrees(Math.PI) === '180deg'
// Math.radians(180) === '3.14rad'
