Açıklamalar

Pozitif dönüş değeri, x ekseninden saat yönünün tersine bir açıyı temsil eder; negatif dönüş değeri, saat yönündeki açıyı temsil eder.

Radyandan dereceye dönüştürmek için dönüş değerini 180/Math.PI ile çarpın.

Bu yöntem, temel alınan C çalışma zamanını çağırır ve tam sonuç veya geçerli giriş aralığı farklı işletim sistemleri veya mimariler arasında farklılık gösterebilir.
