回答： dpb 2016-4-13

I am dividing 60 by 88.8888888888889 in matlab. It is giving result as 0.675000000000000. But when I am doing the same calculation on a calculator, the result is 0.674999999999999.

How to get 0.674999999999999 as result using matlab. Please help.

在 MATLAB Online 中打开

>> 60/88.8888888888889-4*eps(ans)
ans =
 0.674999999999999
>>

Can't expect FP precision to be the same between Matlab and another computing platform; there can be differences even with the same computation of different computers owing to word sizes and implementation.
