|  |  D.15.35.3 newtonPolygonNegSlopes Procedure from librarytropicalNewton.lib(see  tropicalNewton_lib).
 
Example:Usage:
newtonPolygonNegSlopes(g,b); g poly, b int
Return:
list, the negative slopes of the Newton Polygon of g
if b==1, computes root (type poly) instead if (easily) possible
 
Assume:
uniformizingParameter is set and g univariate
 |  | LIB "tropicalNewton.lib";
ring r = (0,t),x,dp;
setUniformizingParameter(t);
poly g = tx2+x+1;
newtonPolygonNegSlopes(g);
==> [1]:
==> 0
==> [2]:
==> -1
// poor man's polynomials over p-adic numbers:
ring s = 0,x,dp;
setUniformizingParameter(3);
poly g = x2+9x+1;
newtonPolygonNegSlopes(g);
==> [1]:
==> 0
