If you want to print several newlines, printf is a good bet. You don't get echo -e everywhere, but printf works nearly the same way wherever you go.

If you want to print a string without a newline, printf can do that everywhere too. printf "%s" "mystring"

If you want to format numbers, printf can also do that for you.

Code:
printf "%.3f\n" 10
10.000

In fact it can do quite a few things, more than I have time to mention here. See man printf for details.
Is there a way where I can combine the floating point number scale along with the string formatting, something like below

Code:
printf "%.3f %s\n" Difference is 10

Difference is 10.000
