D.4.3.1 zeroRadical

Procedure from library assprimeszerodim.lib (see assprimeszerodim_lib).

Usage:
zeroRadical(I[, exactness]); I ideal, exactness int

Assume:
I is zero-dimensional in Q[variables]

Return:
the radical of I

Note:
A final test is applied to the result if exactness != 0 (default), otherwise no final test is done.

Example:
 
LIB "assprimeszerodim.lib";
ring R = 0, (x,y), dp;
ideal I = xy4-2xy2+x, x2-x, y4-2y2+1;
zeroRadical(I);
==> _[1]=y2-1
==> _[2]=x2-x
