Hi all, I'm now back with Xloops project and this is my "hello" to you :-): in ginsh type > a=1/(1-x-x^2); (1-x-x^2)^(-1) > b=series(a,x==0,3); 1+1*x+2*x^2+Order(x^3) > b/2; 1/2*1+1*x+2*x^2+Order(x^3) ^^^^^^ I checked and find out it's not the print() problem so maybe it comes from the expand()? Hope not to have to say "hello" every day :-) Cheers, Son.
