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
