The computation error is less than one ulp 計算誤差小于一個ulp 。
Compared with the traditional algorithm ( computation error is more than 10 percents ) , the computation precision of the proposed algorithm was greatly increased 利用本算法,圖像面積和周長的計算誤差最大不超過2 。
In numerical computation aspect , by implying new computational geometric field , computation error caused by boundary condition was decreased 在數值計算方面,本文采用了新的計算域,減小了由于邊界條件造成的計算誤差。
