The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

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


Type: System.Decimal

A decimal number.

Return Value

Type: System.Decimal

The smallest integral value that is greater than or equal to d. 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(Decimal) method, which supports rounding toward negative infinity.

The following example illustrates the Math.Ceiling(Decimal) method and contrasts it with the Floor(Decimal) method.

Dim values() As Decimal = {7.03d, 7.64d, 0.12d, -0.12d, -7.1d, -7.6d}
Console.WriteLine("  Value          Ceiling          Floor")
For Each value As Decimal In values
   Console.WriteLine("{0,7} {1,16} {2,14}", _
                     value, Math.Ceiling(value), Math.Floor(value))
' The example displays the following output to the console:
'         Value          Ceiling          Floor
'          7.03                8              7
'          7.64                8              7
'          0.12                1              0
'         -0.12                0             -1
'          -7.1               -7             -8
'          -7.6               -7             -8
