histc problem in counting in particular bin

Hello
For data = 0.1:0.02:0.3 and bins = 0.1:0.04:0.3. When I use histc(data, bins), I get histogram frequency = 2 2 2 2 2 1. which is correct.
But when I change bins upto 0.4, I mean bins = 0.1:0.04:0.4, then the histogram frequency = 2 2 3 1 2 1 0 0, which is not correct. It incorrectly counting upper bound in 3rd bin and missing lower bound in 4th bin.
I appreciate any help.

You are assuming that the bin boundaries are calculated with infinite precision, which is impossible. Likewise your data is also not computed in perfect increments of 0.04.

The process is not actually random, but it is complicated . If you have two different ways of calculating the same mathematical quantity, then if there are any differences, you might not get the same result for the two ways.
