#define CMO_ZZ 20
We describe the bignum (multi-precision integer) representation CMO_ZZ in OpenXM. The format is similar to that in GNU MP. (cf. plugin/cmo-gmp.c in the kan/sm1 distribution). CMO_ZZ is defined as follows.
int32 CMO_ZZ | int32 | int32 | int32 |
is a 32bit integer. are unsigned 32bit integers. is equal to . The sign of represents that of the above integer to be expressed. As stated in Section 2, a negative 32bit integer is represented by two's complement.
In OpenXM the above CMO represents the following integer. (.)
Example: If we express int32 by the network byte order, a CMO_ZZ is expressed by
Note that CMO_ZZ 0 is expressed by (CMO_ZZ, 00,00,00,00).
