注意三角函數 (sin(), cos(), tan(), asin(), acos(), atan(), atan2()) 的參數或回傳值的角度皆以弧度為單位。把角度乘上 (Math.PI / 180) 會得到弧度單位，將弧度除以該數則會轉換回一般所用的角度單位。

注意許多數學方法的精度是取決於實作方式的。這意味著不同的瀏覽器可能會得到不同的結果，甚至同一個 JS引擎在不同的作業系統或架構上所得到的結果都有可能相異。

It might be tempting to use Math.round() to accomplish that, but doing so would cause your random numbers to follow a non-uniform distribution, which may not be acceptable for your needs.
