bc 1.06.94-3ubuntu1 (i386 binary) in ubuntu intrepid

 GNU bc is an interactive algebraic language with arbitrary precision which
 follows the POSIX 1003.2 draft standard, with several extensions including
 multi-character variable names, an `else' statement and full Boolean
 expressions. GNU bc does not require the separate GNU dc program.
