Açıklamalar

Bu yöntem bu DateTimedeğerini değiştirmez. Bunun yerine, değeri bu işlemin sonucu olan yeni DateTime bir döndürür.

öğesinin value kesirli kısmı, bir dakikanın kesirli kısmıdır. Örneğin 4,5, 4 dakika, 30 saniye, 0 milisaniye ve 0 değer çizgisine eşdeğerdir.

.NET Framework'te value parametresi en yakın milisaniyeye yuvarlanmıştır. .NET 7 ve sonraki sürümlerde parametresinin Double tam value duyarlığı kullanılır. Ancak kayan nokta matematiğin doğası gereği kesinlik nedeniyle elde edilen duyarlık farklılık gösterir.
