Decimal points

[loperam]

Hello guys

I need to find a way to modify my file so I have my first number with 3 decimal points, comma, space and then my second number 3 decimal points too.

This is an example of my file:
12,10.026
8,6.35
5,5.83
11,7.87

And I need this output:
12.000, 10.026
8.000, 6.350
5.000, 5.830
11.000, 7.870

I think I can use something like: printf "%0.3f\n"
but how can I create a script that can read the whole file and save it in the output format I need?

Thanks a lot for your help

You could use awk.
awk -F\, {printf("%.3f, %.3f\n",$1,$2)}' yourfile

That works great!

Thanks a lot!!
