Could anyone tell me what is wrong with the following code?

>> a=(6.6-5.5)/0.1

a =

11.0000

>> floor(a)

ans =

I suppose I should get ans=11, right? But I got ans=11. If I run the following code, I got the right result

>> a=(2.2-1.1)/0.1

a =

>> floor(a)

ans =

Could anyone tell me what is wrong with the first part?

 sprintf('%.32f',(6.6-5.5)/0.1)
 (6.6-5.5)/sym(0.1)

>> sprintf('%.32f',(6.6-5.5)/sym(1))

ans =

'1.10000000000000008881784197001252'

Now I tried the above code, and I got the wrong result. Is it an inherent flaw in MATLAB, which cannot be fixed completely?
