i am trying to solve a=(4:0.0002:4.20) with format long, but i am getting weird values and not accurated ones like 4.196000000000001 4.196200000000000 4.196400000000001 4.196600000000000 4.196800000000001
But it should be like this 4.196000000000000 4.196200000000000 4.196400000000000 4.196600000000000 4.196800000000000
why matlab is not giving me accurate answer and adding 0.000000000000001 at alternative figures.
