A number with more than x bits where x is the word-length of the computer. On 64-bit computers, bignums have more than 64 bits and are outside the range -2^63..2^63-1. For the curious: The exact definition of x is that it is the number of bits in a C variable of type uintptr_t as defined in stdint.h. See also hugenum.
