       These functions perform arithmetic on integers of arbitrary length. The
       integers are stored using the defined type MINT.	 Pointers  to  a  MINT
       should  be  initialized	using  the function mp_itom(n), which sets the
       initial value to n. Alternatively, mp_xtom(a) may be used to initialize
       a MINT from a string of hexadecimal digits.  mp_mfree(a) may be used to
       release the storage allocated by the  mp_itom(a)	 and  mp_xtom(a)  rou‐

       The  mp_madd(a,b,c), mp_msub(a,b,c) and mp_mult(a,b,c) functions assign
       to their third arguments the  sum,  difference,	and  product,  respec‐
       tively,	of  their  first two arguments.	 The mp_mdiv(a,b,q,r) function
       assigns the quotient and remainder,  respectively,  to  its  third  and
       fourth	arguments.    The  mp_sdiv(a,n,q,r)  function  is  similar  to
       mp_mdiv(a,b,q,r) except that the divisor is an ordinary	integer.   The
       mp_msqrt(a,b,r)	function produces the square root and remainder of its
       first argument.	The mp_mcmp(a,b) function compares the values  of  its
       arguments  and  returns	0 if the two values are equal, a value greater
       than  0 if the first argument is greater than the second, and  a	 value
       less  than   0  if  the second argument is greater than the first.  The
       mp_rpow(a,n,b) function raises a to the	nth  power  and	 assigns  this
       value  to  b.  The mp_pow(a,b ,c,d) function raises a to the bth power,
       reduces the result  modulo c and assigns this value to d. The mp_min(a)
       and   mp_mout(a)	 functions  perform  decimal  input  and  output.  The
       mp_gcd(a,b,c) function finds the greatest common divisor of  the	 first
       two  arguments,	returning  it  in the third argument.  The mp_mtox( a)
       function provides the inverse of mp_xtom(a).  To	 release  the  storage
       allocated by mp_mtox(a) use free() (see malloc(3C)).

       Use the -lmp loader option to obtain access to these functions.

       The function pow() exists in both libmp and libm with widely  differing
       semantics.  This	 is  the  reason exists. exists
       solely for reasons of backward compatibility, and should	 not  be  used
       otherwise. Use the  mp_*() functions instead.  See libmp(3LIB).
