C# .DivRem()

The .DivRem() method calculates the quotient of two numbers and returns the remainder in an output parameter. This method is useful when both the quotient and remainder of a division operation are needed.

Syntax

public static long DivRem(long dividend, long divisor, out long remainder);

Parameters:

• dividend: The number to be divided (type int or long).
• divisor: The number to divide by (type int or long).
• remainder: An output parameter that receives the remainder (type int or long).

Return value:

The method returns the quotient as an int or long, depending on the parameter types used.

Note: This method throws a DivideByZeroException if the divisor is zero.

Example

The following example demonstrates using the .DivRem() method to calculate both quotient and remainder:

using System;

public class Example
{
  public static void Main()
  {
    int dividend = 30;
    int divisor = 7;
    int remainder;

    int quotient = Math.DivRem(dividend, divisor, out remainder);

    Console.WriteLine($"Dividend: {dividend}");
    Console.WriteLine($"Divisor: {divisor}");
    Console.WriteLine($"Quotient: {quotient}");
    Console.WriteLine($"Remainder: {remainder}");
  }
}
