Decimal.Ceiling(Decimal) Method

public:
 static System::Decimal Ceiling(System::Decimal d);

public:
 static System::Decimal Ceiling(System::Decimal d) = System::Numerics::IFloatingPoint<System::Decimal>::Ceiling;

public static decimal Ceiling (decimal d);

static member Ceiling : decimal -> decimal

Public Shared Function Ceiling (d As Decimal) As Decimal

Parameters

Returns

The smallest integral value that is greater than or equal to the d parameter. Note that this method returns a Decimal instead of an integral type.

Examples

The following example illustrates the Ceiling method and contrasts it with the Floor method.

using System;

public class Example
{
   public static void Main()
   {
      decimal[] values = {12.6m, 12.1m, 9.5m, 8.16m, .1m, -.1m,  -1.1m,
                          -1.9m, -3.9m};
      Console.WriteLine("{0,-8} {1,10} {2,10}\n",
                        "Value", "Ceiling", "Floor");
      foreach (decimal value in values)
      Console.WriteLine("{0,-8} {1,10} {2,10}", value,
                        Decimal.Ceiling(value), Decimal.Floor(value));
   }
}

Remarks

The behavior of this method follows IEEE Standard 754, section 4. This kind of rounding is sometimes called rounding toward positive infinity. In other words, if d is positive, the presence of any fractional component causes d to be rounded to the next highest integer. If d is negative, the rounding operation causes any fractional component of d to be discarded. The operation of this method differs from the Floor method, which supports rounding toward negative infinity.
