This is the only storage format for Calc data objects which is not a Lisp list. Large integers are stored as lists of the form @samp{(bigpos @var{d0} -@var{d1} @var{d2} @dots{})} for positive integers 1000000 or more, or -@samp{(bigneg @var{d0} @var{d1} @var{d2} @dots{})} for negative integers -@mathit{-1000000} or less. Each @var{d} is a base-1000 ``digit,'' a Lisp integer -from 0 to 999. The least significant digit is @var{d0}; the last digit, +@var{d1} @var{d2} @dots{})} for sufficiently large positive integers +(where ``sufficiently large'' depends on the machine), or +@samp{(bigneg @var{d0} @var{d1} @var{d2} @dots{})} for negative +integers. Each @var{d} is a base-@expr{10^n} ``digit'' (where again, +@expr{n} depends on the machine), a Lisp integer from 0 to +99@dots{}9. The least significant digit is @var{d0}; the last digit, @var{dn}, which is always nonzero, is the most significant digit. For -example, the integer @mathit{-12345678} is stored as @samp{(bigneg 678 345 12)}. +example, the integer @mathit{-12345678} might be stored as +@samp{(bigneg 678 345 12)}. The distinction between small and large integers is entirely hidden from the user. In @code{defmath} definitions, the Lisp predicate @code{integerp} |
