Decimal.Ceiling Method (Decimal)

 

Returns the smallest integral value that is greater than or equal to the specified decimal number.

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

Public Shared Function Ceiling (
	d As Decimal
) As Decimal

Parameters

d
Type: System.Decimal

A decimal number.

Return Value

Type: System.Decimal

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.

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.

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

Module Example
   Public Sub Main()
      Dim values() As Decimal = {12.6d, 12.1d, 9.5d, 8.16d, .1d, -.1d,  
                                 -1.1d, -1.9d, -3.9d}
      Console.WriteLine("{0,-8} {1,10} {2,10}", 
                        "Value", "Ceiling", "Floor")
      Console.WriteLine()
      For Each value As Decimal In values
      Console.WriteLine("{0,-8} {1,10} {2,10}", value,
                        Decimal.Ceiling(value), Decimal.Floor(value))
      Next                                     
   End Sub
End Module
