Question

i am using toRad() function in javascript as below

    var alpha1 = brng.toRad();

but when i run my code it gives an error saying “brng.toRad is not a function”

How does it work in java script, do i need to import some library???

Answer 1

You can also do this:

Number.prototype.toRad = function () { return this * Math.PI / 180; }

var oneeighty = 180;
console.log( oneeighty.toRad() ); // 180 degrees = Pi radians
