DESCRIPTION
       These routines perform arithmetic on integers of arbitrary length.  The
       integers are stored using the defined type MINT.	 Pointers  to  a  MINT
       can be initialized using the function itom which sets the initial value
       to n.  After that, space is managed automatically by the routines.

       madd, msub and mult assign  to  c  the  sum,  difference	 and  product,
       respectively,  of  a  and  b.  mdiv assigns to q and r the quotient and
       remainder obtained from dividing a by b.	 sdiv is like mdiv except that
       the divisor is a short integer n and the remainder is placed in a short
       whose address is given as r.  msqrt produces the integer square root of
       a  in  b and places the remainder in r.	rpow calculates in c the value
       of a raised to the (``regular'' integral) power n, while pow calculates
       this  with  a  full  multiple  precision	 exponent  b and the result is
       reduced modulo m.  gcd returns the greatest common denominator of a and
       b  in  c,  and  invert  computes c such that a*c mod b = 1, for a and b
       relatively prime.  mcmp returns a negative, zero	 or  positive  integer
       value  when  a  is less than, equal to or greater than b, respectively.
       move copies a to b.  min and mout do decimal  input  and	 output	 while
       omin  and  omout	 do  octal input and output.  More generally, fmin and
       fmout do decimal input and output using file f, and m_in and  m_out  do
       I/O  with arbitrary radix n.  On input, records should have the form of
       strings of digits terminated  by	 a  newline;  output  records  have  a
       similar form.

       Programs	 which	use  the multiple-precision arithmetic library must be
       loaded using the loader flag -lmp.

DIAGNOSTICS
       Illegal operations and running out of memory produce messages and  core
       images.

BUGS
       Bases for input and output should be <= 10.

       dc(1) and bc(1) don't use this library.

       The input and output routines are a crock.

       pow is also the name of a standard math library routine.
