О пакете: Fixed length integer arithmetic.
Описание:
This module provides a set of functions to perform arithmetic on fixed length but arbitrarily large bit strings implemented on top of the GMP library low level functions (see http://gmplib.org/manual/Low_002dlevel-Functions.html). Numbers are represented as arrays of GMP mp_limb_t integers (usually, the native unsigned int) packed into Perl scalars without any additional wrapping. The bit length of the strings passed to the module must be a multiple of the mp_limb_t bit size (32 and 64 bits for 32bit and 64bit machines respectively). Most operations do not check that condition and their results are unspecified when arguments with non conforming sizes are used. Also, the strings passed must by internally aligned on a mp_limb_t boundary. That usually means not using the four argument variant of `substr' on any scalar that would be passed to Math::GMPn. For instance: $a = ...; $b = ...; substr($a, 0, 3, ""); mpn_add($r, $a, $b); # croaks! When strings of different length are used on the same operation, the result lenght is equal to that of the largest input. For instance, adding a 128bit string and a 256bit string will output a 256bit string. Overflows are silently discarded.
