@defvar integer-width
The value of this variable is a nonnegative integer that is an upper
bound on the number of bits in a bignum. Integers outside the fixnum
range are limited to absolute values less than 2@sup{@var{n}}, where
@var{n} is this variable's value. Attempts to create bignums outside

this range result in an integer overflow error. Setting this variable
to zero disables creation of bignums; setting it to a large number can
cause Emacs to consume large quantities of memory if a computation
