Fehler (Error) edit
Bei einem Kreis mit Radius r = 1 [LE]:
- Konstruierte Seite des Quadrates s = 1,77245384141934376... [LE]
- Soll-Seite des Quadrates ss = = 1,772453850905516... [LE]
- Absoluter Fehler = s - ss = -0,000000009486172... = -9,486...E-9 [LE]
- Fläche des konstruierten Quadrates A = s2 = 3,141592619962188... [FE]
- Soll-Fläche des Quadrates As = = 3,141592653589793... [FE]
- Absoluter Fehler = A - As = -0,000000033627605... = -3,3627...E-8 [FE]
- Fazit: Sieben Nachkommastellen sind gleich denen von bzw. sind gleich denen von .
- Bei einem Kreis mit dem Radius r = 1000 km wäre der Fehler der Seite s ≈ -9,5 mm
- Bei einem Kreis mit dem Radius r = 10 m wäre der Fehler der Fläche A ≈ -3,4 mm2
- Bei einem Kreis mit dem Radius r = 100 km wäre der Fehler des halben Kreisumfanges U/2 ≈ -3,4 mm
In a circle of radius r = 1 [unit length, ul]:
- Constructed side of the square s = 1,77245384141934376... [ul]
- Target side of the square ss = = 1,772453850905516... [ul]
- Absolute error = s - ss = -0,000000009486172... = -9,486...E-9 [ul]
- Surface of the constructed square A = s2 = 3,141592619962188... [unit area, ua]
- Target area of the square As = = 3,141592653589793... [ua]
- Absolute error = A - As = -0,000000033627605... = -3,3627...E-8 [ua]
- Conclusion: seven decimal places are equal to those of respectively equal to those of .
- In a circle of radius r = 1000 km would be the fault of the page s ≈ -9.5 mm
- In the case of a circle with the radius r = 10 m would be the error of the surface A ≈ -3.4 mm2
- In a circle of radius r = 100 km, the error of the half circumference would U/2 ≈ -3.4 mm
