例子

VBA：

Sub Example_AngleToReal()
    ' This example passes several different strings representing
    ' an angle in different units to be converted to radians.
    
    Dim angAsStr As String
    Dim unit As Integer
    Dim angAsReal As Double
    
    ' Convert the angle given in degrees unit to a real
    angAsStr = "45"
    unit = acDegrees
    angAsReal = ThisDrawing.Utility.AngleToReal(angAsStr, unit)
    MsgBox "45 degrees converts to " & angAsReal & " radians.", , "AngleAsReal Example"
    
    ' Convert the angle given in degrees/minutes/seconds unit to Radians
    angAsStr = "45d0' 0"""
    unit = acDegreeMinuteSeconds
    angAsReal = ThisDrawing.Utility.AngleToReal(angAsStr, unit)
    MsgBox "45 degrees, 0 minutes, 0 seconds converts to " & angAsReal & " radians.", , "AngleAsReal Example"
    
    ' Convert the angle given in grads unit to Radians
    angAsStr = "50"
    unit = acGrads
    angAsReal = ThisDrawing.Utility.AngleToReal(angAsStr, unit)
    MsgBox "50 grads converts to " & angAsReal & " radians.", , "AngleAsReal Example"
    
End Sub
