C# Math Round(Decimal)

Description

Math Round(Decimal) rounds a decimal value to the nearest integral value.

Syntax

Math.Round(Decimal) has the following syntax.

public static decimal Round(
  decimal d
)

Parameters

Math.Round(Decimal) has the following parameters.

• d - A decimal number to be rounded.

Returns

Math.Round(Decimal) method returns The integer nearest parameter d. If the fractional component of d is halfway between two integers, one of which is even and the other odd, the even number is returned. Note that this method returns a Decimal instead of an integral type.

Example

In the following example, because the floating-point value .1 has no finite binary representation, the first call to the Round(Decimal) method with a value of 11.5 returns 11 instead of 12.

using System;//  w w w  .  j a  va  2s  . c o  m

public class Example
{
    public static void Main()
   {
      decimal value = 11.1M;
      Console.WriteLine("{0} --> {1}", value, Math.Round(value));

    }
}

The code above generates the following result.
