NAME             dc -- desk calculator

SYNOPSIS         dc

DESCRIPTION      dc is an arbitrary precision integer arithmetic package.
                 The overall structure of dc is a stacking (reverse Polish)
                 calculator. The following constructions are recognized by
                 the calculator:

                 number
                    The value of the number is pushed on the stack. If the
                    number starts with a zero, it is taken to be octal,
                    otherwise it is decimal.

                 + - * / %
                 The top two values on the stack are added (), subtracted
                     (--), multiplied (*), divided (*) or remaindered (%) The
                     two entries are popped off of the stack, the result is
                     pushed on the stack in their place.

                 sx
                      The top of the stack is popped and stored into a
                      register named x, where x may be any character.

                 lx
                      The value in register x is pushed on the
                      stack. The register x is not altered.

                 d
                      The top value on the stack is pushed on the
                      stack. Thus the top value is duplicated.

                 p
                      The top value on the stack is printed in decimal. The
                      top value remains unchanged.

                 f
                      All values on the stack are popped off and
                      printed in decimal.

                 r
                      All values on the stack are popped.

                 q
                                    exit.

                 h
                      print brief synopsis of commands to dc.

                       new--line
                       space
                         ignored.
