The computation error is less than one ulp 計(jì)算誤差小于一個(gè)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(jì)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(shù)值計(jì)算方面,本文采用了新的計(jì)算域,減小了由于邊界條件造成的計(jì)算誤差。
