A
bignum system in a
computer or program allows internal representation of arbitrarily large
integers or arbitrarily precise
rational numbers, by storing numbers as digit lists which can grow using dynamically allocated memory. First implemented in MacLISP
?, it is implemented in most modern
lisps and in many other languages (
Java,
Ruby,
Python). The
VAX/
VMS operating system offered bignum facilities as a collection of [string functions]
?. The [GNU Multi-Precision Library]
?
is a free
C library that offers bignum features. All [computer algebra]
? systems contain bignum facilities.
