7.7.5.0. intRoots
Procedure from library dmodapp.lib (see dmodapp_lib).

Usage:
isInt(L); L a list

Return:
list

Purpose:
extracts integer roots from a list given in bFactor format

Assume:
The input list must be given in the format of bFactor.

Note:
Parameters are treated as integers.

Example:
 
LIB "dmodapp.lib";
ring r = 0,x,dp;
list L = bFactor((x-4/3)*(x+3)^2*(x-5)^4); L;
==> [1]:
==>    _[1]=5
==>    _[2]=4/3
==>    _[3]=-3
==> [2]:
==>    4,1,2
intRoots(L);
==> [1]:
==>    _[1]=5
==>    _[2]=-3
==> [2]:
==>    4,2
