1、數(shù)值分析上機(jī)報(bào)告數(shù)值分析上機(jī)報(bào)告三、求解結(jié)果三、求解結(jié)果四、結(jié)果分析四、結(jié)果分析有效位數(shù)n順序100100001000000從大到小633從小到大566可以得出，算法對誤差的傳播又一定的影響，在計(jì)算時(shí)選一種好的算法可以使結(jié)果更為精確。從以上的結(jié)果可以看到從大到小的順序?qū)е麓髷?shù)吃小數(shù)的現(xiàn)象，容易產(chǎn)生較大的誤差，求和運(yùn)算從小數(shù)到大數(shù)算所得到的結(jié)果才比較準(zhǔn)確。PleaseInputanN(N1):10^2ThevalueofSnusingdi
