D.14.4.5 direct_boolean_poly

Procedure from library polybori.lib (see polybori_lib).

Usage:
boolean_poly(ps[, rb]); ps polynomial, rb boolean ring

Return:
default: polynomial ps in the representation of the boolean ring rb==boolean_poly_ring(basering); optional input: boolean ring rb

Example:
 
LIB "polybori.lib";
ring r0=2,x(1..4),lp;
bring rb=r0;
poly f=x(1)^2+2*x(2)*(x(3))-x(4)^3;
direct_boolean_poly(f);
==> x(1) + x(4)
direct_boolean_poly(f,rb);
==> x(1) + x(4)
ring r1=0,x,Dp;
poly f=x3+2x+1;
direct_boolean_poly(f);
==> x + 1
ring r2=32003,(x,y,z),Dp;
poly f=xyz+20*x^2*y-3*xz+15;
direct_boolean_poly(f);
==> x*y*z + x*z + 1
