[0.-0.4) contains 0, so result is 1
[0.4-0.8) does not contain any number in [0 1 2 3 4], so result is 0
[0.8-1.2) contains 1, so result is 1
[1.2-1.6) does not contain any number in [0 1 2 3 4], so result is 0
[1.6-2.) does not contain any number in [0 1 2 3 4], so result is 0
[2.-2.4) contains 2, so result is 1
[2.4-2.8) does not contain any number in [0 1 2 3 4], so result is 0
[2.8-3.2) contains 3, so result is 1
[3.2-3.6) does not contain any number in [0 1 2 3 4], so result is 0
[3.6-4.] contains 4, so result is 1
