Could someone please explain the following behaviour of mod block. (See image attached) There are two problems here. the output of mod(1,1) is not zero the output of mod(2,1) is a very less positive number.

Hello, Whenever we do arithmatic operations with the floating point variables there is a small precision error associated which leads to these results.This can be removed by subtracting the eps value and then apply mod. I'm not able to exactly reproduce your case but hope this and this would help you.
You can also look through eps and Math/Algorithms in this link . Hope this helps.
