RingZZ    --    the ring of integers


Syntax
RingZZ(): RING

Description
This function returns the ring of integers. It is useful when you want to use ZZ inside define/enddefine .

NOTE: calling RingZZ twice gives the same identical ring, whereas calling NewPolyRing or NewFractionField return each time a new ring.

Example
/**/  Two := RingElem(RingZZ(), 2);   Two;
2
/**/  type(Two);
RINGELEM;
/**/  IsZZ(RingOf(Two));
true
/**/  IsQQ(RingOf(Two));
false
