Question on bc - basic calculator

12/11/2007, 03h27

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/

So how can i use bc to solve some radical problem ,like this
expression a(ab-xb)/axb=

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