.NET Framework 2.0
Represents a 16.16 fixed-point number.

'Declaration Public Structure FixedPoint Implements IComparable, IFormattable, IConvertible 'Usage Dim instance As FixedPoint
public final class FixedPoint extends ValueType implements IComparable, IFormattable, IConvertible
JScript suports the use of structures, but not the declaration of new ones.
This structure is used to interoperate with the various types in Windows Mobile Direct 3D that have fixed-point interfaces. The internal representation of this class is an Int32 structure.
The following example shows how you can use a FixedPoint structure.
' The following code is from the ' Direct3D Mobile Fixed Point Billboard Sample. ' It uses FixedPoint to position meshes of trees randomly. ' Initialize the tree data Dim i As Integer For i = 0 To numberTrees - 1 Dim t As New Tree() ' Position the trees randomly Do Dim fTheta As Single = 2.0F * _ System.Convert.ToSingle(Math.PI) * _ System.Convert.ToSingle(rand.NextDouble()) Dim fRadius As Single = 25.0F + 55.0F * _ System.Convert.ToSingle(rand.NextDouble()) Dim position As Vector3Fixed position.X = CType(fRadius * _ System.Convert.ToSingle( _ Math.Sin(fTheta)), FixedPoint) position.Z = CType(fRadius * _ System.Convert.ToSingle(Math.Cos(fTheta)), FixedPoint) position.Y = CType(HeightField( _ System.Convert.ToSingle(position.X), _ System.Convert.ToSingle(position.Z)), FixedPoint) t.Position = position Loop While Not IsTreePositionValid(t.Position)
