Decimal.Modulus Operator

Returns the remainder resulting from dividing two specified Decimal values.

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

public static decimal operator %(
	decimal d1,
	decimal d2


Type: System.Decimal
A Decimal (the dividend).
Type: System.Decimal
A Decimal (the divisor).

Return Value

Type: System.Decimal
The Decimal remainder resulting from dividing d1 by d2.


d2 is zero.


The return value is less than MinValue or greater than MaxValue.

The following code example creates several pairs of Decimal values and calculates the remainders resulting from dividing the two values with the Modulus operator.

// Example of the decimal multiplication, division, and modulus 
// operators.
using System;

class Example
   const string dataFmt = "   {0,-18}{1,31}";

   // Display decimal parameters and their product, quotient, and 
   // remainder.
   public static void ShowDecimalProQuoRem(System.Windows.Controls.TextBlock outputBlock, decimal Left, decimal Right)
      outputBlock.Text += "\n";
      outputBlock.Text += String.Format(dataFmt, "decimal Left", Left) + "\n";
      outputBlock.Text += String.Format(dataFmt, "decimal Right", Right) + "\n";
      outputBlock.Text += String.Format(dataFmt, "Left * Right", Left * Right) + "\n";
      outputBlock.Text += String.Format(dataFmt, "Left / Right", Left / Right) + "\n";
      outputBlock.Text += String.Format(dataFmt, "Left % Right", Left % Right) + "\n";

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
      outputBlock.Text +=
          "This example of the decimal multiplication, division, " +
          "and modulus \noperators generates the following " +
          "output. It displays the product, \nquotient, and " +
          "remainder of several pairs of decimal objects." + "\n";

      // Create pairs of decimal objects.
      ShowDecimalProQuoRem(outputBlock, 1000M, 7M);
      ShowDecimalProQuoRem(outputBlock, -1000M, 7M);
          new decimal(1230000000, 0, 0, false, 7), 0.0012300M);

This example of the decimal multiplication, division, and modulus
operators generates the following output. It displays the product,
quotient, and remainder of several pairs of decimal objects.
