Installation of Bc
Install bc by running the following commands:
./configure --prefix=/usr --with-readline && make
To test bc, run the commands below. There is quite a bit of output, so you may want to redirect it to a file. There are a very small percentage of tests (10 of 12,144) that will indicate a roundoff error at the last digit.
echo "quit" | ./bc/bc -l Test/checklib.b
Now, as the root user:
make install
Command Explanations

option enables Readline support in
interactive mode.
