Create a file  ~/bc.conf with your desired settings (like your
mentioned scale=4).
Start bc with this file as argument and force interactive mode:
  bc -i bc.conf
This will evaluate bc.conf and instead of quitting after EOF it will drop you to
a bc prompt for further evaluation.
You may add an alias or a wrapper script for this at your will.
