how do i make my program take very large positive numbers without using double precision integer type. for instance:
the user should be able to enter a number like:
5245456638463644648646486464348443466648436446
and get something like:
4243545636758689184912673254783849162783326564 as its quotient and 76586798707897 as its remiander.
i’ll also like to know if its never possible to get that using just “int type”. thanx to all. - March 17, 2008 at 2:34 pm #3359HumayanParticipant
Usually what is done in this case is one is required to write a large number module for your program. A array of the smallest integer type on your machine is usually used ( a short type or something like that ). You will usually use an array like:
short largeNumber [ NUMBER_OF_DIGITS ];
and then you will represent large numbers like:
12345….
largeNumber [ 0 ] = 1largeNumber [ 1 ] = 2
largeNumber [ 2 ] = 3
largeNumber [ 3 ] = 4
largeNumber [ 4 ] = 5
……..
then you write functions to read , write and do mathematical computations on the arrays like:
123456789101112int * num;<br />int * num2;<br />int * sum;<br /><br />initialize ( num , size ); //allocate memory<br />initialize ( num2 , size ); //allocate memory<br /><br />sum = add ( num , num2 ); //sum 2 large numbers<br /><br />printf ( "the sum is n" );<br />printLargeNumber ( sum ); //output sum<br />
