I have a file which i catenate and using the fields in the file, I would like to get sqrt of it. I tried to man the function but it normally would need an echo as well as bc.
Why?
Why cannot you use awk's 'sqrt'?

END{
printf("the sqrt of %d is %d\n", $2,$1);
}
However, it does not work. Please help.
Thanks.
