ok, it isn't normalize, but a very small function called npWrite
void npWrite (number &a)
{
if ((long)a > (npPrimeM >>1)) StringAppend("-%d",(int)(npPrimeM-
((long)a)));
else StringAppend("%d",(int)((long)a));
}
This is set to the current ring
in numbers.cc
n->nWrite

It's probably just a function pointer.
void(*nNormalize)(number &a);
But I am not sure about side effects.

I don't see the problem, since -10 == 99 mod GF(109).Even if it is undesired
that they print differently how come it is 'major'? Wh
