例子

VBA：

Sub Example_AngleToString()
    ' This example converts a radian value to several different
    ' strings representing the value in different units.
    
    Dim angAsRad As Double
    Dim unit As Integer
    Dim precision As Long
    Dim angAsString As String
    angAsRad = 0.785398163397448
    unit = acDegrees
    precision = 6
    
    ' Convert the radian value to degrees with a precision of 6
    angAsString = ThisDrawing.Utility.AngleToString(angAsRad, unit, precision)
    MsgBox "0.785398163397448 radians =  " & angAsString & " degrees", , "AngleAsString Example"
    
    ' Convert the radian value to degrees/Minutes/Seconds with a precision of 6
    unit = acDegreeMinuteSeconds
    angAsString = ThisDrawing.Utility.AngleToString(angAsRad, unit, precision)
    MsgBox "0.785398163397448 radians =  " & angAsString, , "AngleAsString Example"
    
    ' Convert the radian value to grads with a precision of 6
    unit = acGrads
    angAsString = ThisDrawing.Utility.AngleToString(angAsRad, unit, precision)
    MsgBox "0.785398163397448 radians =  " & angAsString, , "AngleAsString Example"
    
End Sub
