# Math.DivRem Method (Int32, Int32, Int32)

.NET Framework 3.0
Calculates the quotient of two 32-bit signed integers and also returns the remainder in an output parameter.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

## Syntax

```public static int DivRem (
int a,
int b,
out int result
)
```
```public static int DivRem (
int a,
int b,
/** @attribute OutAttribute() */ /** @ref */ int result
)
```
```Not applicable.
```

#### Parameters

a

The System.Int32 that contains the dividend.

b

The System.Int32 that contains the divisor.

result

The System.Int32 that receives the remainder.

#### Return Value

The System.Int32 containing the quotient of the specified numbers.

## Exceptions

Exception typeCondition

DivideByZeroException

b is zero.

## Example

The following code example demonstrates the DivRem method.

```// This example demonstrates Math.DivRem()
//                           Math.IEEERemainder()
using System;

class Sample
{
public static void Main()
{
int int1 = Int32.MaxValue;
int int2 = Int32.MaxValue;
int intResult;
long long1 = Int64.MaxValue;
long long2 = Int64.MaxValue;
long longResult;
double doubleResult;
double divisor;
String nl = Environment.NewLine;
//
Console.WriteLine("{0}Calculate the quotient and remainder of two Int32 values:", nl);
intResult = Math.DivRem(int1, 2, out int2);
Console.WriteLine("{0}/{1} = {2}, with a remainder of {3}.", int1, 2, intResult, int2);
//
Console.WriteLine("{0}Calculate the quotient and remainder of two Int64 values:", nl);
longResult = Math.DivRem(long1, 4, out long2);
Console.WriteLine("{0}/{1} = {2}, with a remainder of {3}.", long1, 4, longResult, long2);
//
String str1 = "The IEEE remainder of {0:e}/{1:f} is {2:e}";
divisor = 2.0;
Console.WriteLine("{0}Divide two double-precision floating-point values:", nl);
doubleResult = Math.IEEERemainder(Double.MaxValue, divisor);
Console.Write("1) ");
Console.WriteLine(str1, Double.MaxValue, divisor, doubleResult);

divisor = 3.0;
doubleResult = Math.IEEERemainder(Double.MaxValue, divisor);
Console.Write("2) ");
Console.WriteLine(str1, Double.MaxValue, divisor, doubleResult);
Console.WriteLine("Note that two positive numbers can yield a negative remainder.");
}
}
/*
This example produces the following results:

Calculate the quotient and remainder of two Int32 values:
2147483647/2 = 1073741823, with a remainder of 1.

Calculate the quotient and remainder of two Int64 values:
9223372036854775807/4 = 2305843009213693951, with a remainder of 3.

Divide two double-precision floating-point values:
1) The IEEE remainder of 1.797693e+308/2.00 is 0.000000e+000
2) The IEEE remainder of 1.797693e+308/3.00 is -1.000000e+000
Note that two positive numbers can yield a negative remainder.
