Question on bc - basic calculator

am 12.11.2007 04:27:44 von linq936

Hi,
I am new to bc, i just tried 2/5, but it returns 0. I think somehow
I should turn on some decimal setup, but I do not see how to do it. I
also tried 2.0/5.0, it does the same.

Any pointer?

Thanks.

bc -l
from the command line, or
scale=8
inside bc. This sets up the number of decimal places it uses/

A calculator is not the best tool to implement a computer algebra
system.
