I am sharing a code snippet.
I am getting a syntax error in line of subtraction that says something like:
syntax error: invalid arithmetic operator (error token is ".0985146")
This is the line that gives error.
Appreciate your help.
I am assuming you are using bash or perhaps a POSIX shell like dash.
Your error is telling you that it is not possible to do such a task as these shells have INTEGER arithmetic only.
If you need floating/fixed point arithmetic then you will have to do workarounds using, bc, dc, python, perl, awk or any other methods that are capable of such mechanisms.
(Just an observation, you have both, ${barr1[$i]} and also ${harr1[j]} are these correct?)
EDIT:
Note the second one should have ${harr1[$j]}
An example longhand using INTEGER arithmetic and FIXED point, OSX 10.14.6, default bash terminal:
