using bc with floating point number in files
Hi,
I' using bash and I would like to use "bc" to compute the ratio of of two numbers and assign the ratio to a variable.
The numbers are in a file, e.g.
196.304492
615.348986

Any idea how to do it?
N.B. I cannot change the file to have 196.304492 / 615.348986 as the file is produced by another code.

Thank you for your help,
Sarah
