public static System.Numerics.BigInteger DivRem (System.Numerics.BigInteger dividend, System.Numerics.BigInteger divisor, out System.Numerics.BigInteger remainder);
static member DivRem : System.Numerics.BigInteger * System.Numerics.BigInteger * BigInteger -> System.Numerics.BigInteger
Public Shared Function DivRem (dividend As BigInteger, divisor As BigInteger, ByRef remainder As BigInteger) As BigInteger
Параметры
- dividend
- BigInteger
Значение, которое необходимо разделить.The value to be divided.
- divisor
- BigInteger
Значение, на которое необходимо разделить.The value to divide by.
- remainder
- BigInteger
После выполнения данного метода содержит значение BigInteger, представляющее остаток от деления.When this method returns, contains a BigInteger value that represents the remainder from the division. Этот параметр передается неинициализированным.This parameter is passed uninitialized.
Возвращаемое значение
Частное от деления.The quotient of the division.
Исключения
Значение параметра divisor
равно нулю (0).divisor
is 0 (zero).
Примеры
В следующем примере создается массив BigInteger значений.The following example creates an array of BigInteger values. Затем он использует каждый элемент в качестве частного в операции деления, которая использует Divide метод, оператор деления (/) и DivRem метод.It then uses each element as the quotient in a division operation that uses the Divide method, the division operator (/), and the DivRem method.

Комментарии
Этот метод сохраняет как частное, так и остаток, полученные в результате целочисленного деления.This method preserves both the quotient and the remainder that results from integer division. Если вы не заинтересованы в оставшейся части, используйте метод Divide или оператор деления. Если вы заинтересованы только в оставшейся части, используйте метод Remainder .If you are not interested in the remainder, use the Divide method or the division operator; if you are only interested in the remainder, use the Remainder method.
Знак возвращаемого значения совпадает со remainder
знаком dividend
параметра.The sign of the returned remainder
value is the same as the sign of the dividend
parameter.
Поведение DivRem метода идентично поведению Math.DivRem метода.The behavior of the DivRem method is identical to that of the Math.DivRem method.
