Floating point numeric problem

I encounter a problem which I cannot understand.
a = 1.228269:0.000001:1.22828;
b = 1.228265:0.000001:1.22828;
ismember(a,b)
>> ismember(a,b)
ans =
1×12 logical array
0 1 0 1 1 1 1 1 1 1 1 1
It is clearly to see that the logical array is not compatible with the values in vectors a and b. An expert has suggested that this has to do with the floating point numerics, do anyone can explain what happened to this example and how to we circumvent it ? Thanks a lot !

You can circumvent it using the ismembertol function (in R2015a and later versions).
