NAME    pmod - integral power of an integer modulo a specified integerSYNOPSIS    pmod(x, n, md)TYPES    x		integer    n		nonnegative integer    md		integer    return	integerDESCRIPTION    pmod(x, n, md) returns the integer value of the canonical residue    of x^n modulo md, where the set of canonical residues is determined    by md and bits 0, 2, and 4 of config("mod") (other bits are ignored).    If md is zero, the value is simply x^n.    For nonzero md, the canonical residues v modulo md are as follows:		config("mod")	  md > 0	      md < 0		    0		0 < v < md	   md < v < 0		    1	      -md < v < 0	    0 < v < -md		    4		0 < v < md	    0 < v < -md		    5	      -md < v < 0	   md < v < 0		   16	    -md/2 < v <= md/2	md/2 <= v < -md/2		   17	   -md/2 <= v < md/2	 md/2 < v <= -md/2		   20	    -md/2 < v <= md/2	 md/2 < v <= -md/2		   21	   -md/2 <= v < md/2	md/2 <= v < -md/2EXAMPLE    ; c = config("mod",0)    ; print pmod(2,3,10), pmod(2,5,10), pmod(2,3,-10), pod(2,5,-10)    8 2 -2 -8    ; c = config("mod",16)    ; print pmod(2,3,10), pmod(2,5,10), pmod(2,3,-10), pmod(2,5,-10)    -2 2 -2 2LIMITS    noneLINK LIBRARY    NUMBER *qpowermod(NUMBER *x, NUMBER *n, NUMBER *md)SEE ALSO    mod, minv## Copyright (C) 1999  Landon Curt Noll#### Calc is open software; you can redistribute it and/or modify it under## the terms of the version 2.1 of the GNU Lesser General Public License## as published by the Free Software Foundation.#### Calc is distributed in the hope that it will be useful, but WITHOUT## ANY WARRANTY; without even the implied warranty of MERCHANTABILITY## or FITNESS FOR A PARTICULAR PURPOSE.
