I 'm designing a package to handle large (signed) integers (in pascal), the size of these 
integers are merely bounded by the available memory.  First a trivial question: Does 
anyone have a fast (faster than euclidean division) algorithm to calculate x mod n?  
Performance:
What number of cycles are acceptable/fast/extraordinary to multiply/add x-digit 
numbers?
What functions (besides the basics (+,-,*,/), and x mod n, x^d mod n) should such a a 
package contain?
If I 'm forgetting something, let me know.
