MATLAB: Matlab ROUND function not rounding small decimals away

It is just a display issue and the fact that IEEE double cannot represent the numbers exactly. E.g.,

>> num2strexact(66.6)
ans =
6.6599999999999994315658113919198513031005859375e1

So the closest number to 66.6 that is representable in IEEE double, when converted to an exact decimal equivalent, in fact has all of those 9's and the 4 at the end. Rounding the number to the nearest tenth or hundredth etc isn't going to change anything because there isn't anything closer to 66.6 in the IEEE double set that you can round to.

Similarly,

>> num2strexact(59.4)
ans =
5.939999999999999857891452847979962825775146484375e1
