Hi rohit_shinez...
(Apologies for any typos.)
In bash? Hmm, awk - most probably as it has builtin scientific maths and floating point capability, but I am no expert.
Bash has ONLY integer maths and that is its limitation. As I quoted before if you have access to tools/utilities that can do floats, Python, Perl, bc, dc, or others then it is possible as is creating your own FIXED point maths calculator. (Note: 'maths' as I am UKan.)
A simple fully POSIX compliant example of making a floating point number divided by an integer like your case. All values are global here to make for an easy to understand to the problems involved if you don't have any decent tools to manipulate scientific and FP values.
Also POSIX does NOT allow x**y hence the multiplier function. Fortunately 'bash' CAN handle this in integer mode only but not shown:
Result for this maths dilemma: OSX 10.14.3, default bash terminal calling dash...
You now see your problem...
HOWEVER; as I also quoted 'ksh' supports floating point arithmetic, including, float**another_float , which I have used often...
Unless your system does NOT have Python support then the code you have already would probably be better suited translated to awk.
I will pass those thoughts on to our awk experts...
I hope this helps wrap things up...
Hi ,
this is the first time i use bc to calculate and i would have decimal result , i use the following :
toto=400;scale=1 echo $toto / 1000|bc
scale to adjust the numbers after the command would have in this case 0.4 as result and i wonder why i have always 0 as result.
Somebody can... (2 Replies)

About 4 years ago I wrote this tool inspired by Rob Urban's collect tool for DEC's Tru64 Unix. What makes this tool as different as collect was in its day is its ability to run at a low overhead and collect tons of stuff. I've expanded the general concept and even include data not available in... (0 Replies)
