This chapter contains various utilities that do not fit conveniently into other chapters. Programs include a command line calculator, several utilities for manipulating text and graphics, and a program to interface with a palm-pilot.
The bc package contains an arbitrary precision numeric processing language.

Install bc by running the following commands:
sed -i '/PROTO.*readline/d' bc/scan.l && sed -i '/flex -I8/s/8//' configure && sed -i '/stdlib/a #include <string.h>' lib/number.c && sed -i 's/program.*save/static &/' bc/load.c && ./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:
sed -i '/PROTO.*readline/d' bc/scan.l: This command fixes the Readline library call.
sed -i '/flex -I8/s/8//' configure: This command fixes the Flex invocation.
sed -i '/stdlib/a #include <string.h>' lib/number.c: This command inserts a missing header.
sed -i 's/program.*save/static &/' bc/load.c: This command fixes a segfault when running bc with bc -l.
--with-readline: This option enables Readline support in interactive mode.
