00020   sc_nbexterns.h -- External functions for both sc_signed and sc_unsigned
00021                     classes. These functions work on two parameters u and
00022                     v, and copy the result to the first parameter u. This
00023                     is also the reason that they are suffixed with _on_help.
00024  
00025                     The vec_* functions are called through either these
00026                     functions or those in sc_nbfriends.cpp. The functions in
00027                     sc_nbfriends.cpp perform their work on two inputs u and v,
00028                     and return the result object.
