dc (desk calculator) is a cross-platform reverse-Polish calculator which supports arbitrary-precision arithmetic. It was written by Lorinda Cherry and Robert Morris at Bell Labs. dc is one of the oldest Unix utilities, preceding even the development of the C programming language. Like other utilities of that vintage, it has a powerful set of features but terse syntax. Although the bc calculator program (which uses infix notation) was traditionally implemented on top of dc, the modern GNU implementation of dc bases off of bc.
