OpenSSL includes an implementation of multiprecision arithmetic,
used for dealing with the large numbers used in public-key cryptography and a few other cryptographic algorithms.

BIGNUM library internal functions "to facilitate debugging and extending the library.
They are not to be used by applications."

Other popular [http://en.wikipedia.org/wiki/Arbitrary-precision_arithmetic multiprecision libraries and tools] that perhaps might be useful for testing OpenSSL's multiprecision implementation include:
