Jean for the Gramm Schmidt POLYROOTS doc, i adjusted decimal points to 15 for the maple solve and got: -0.906181463330827 for one of the solves on pages 4,
compared with the Smath solution of: -0.906181339783194 on page 3.


No idea about accuracy of numbers, but thought i would just have a slightly deeper look,

all the best,

John

The solve(4) organizes the roots in order, Maple not but OK for Lagrange.
solve warrants at least 4 decimals, most of the times ~ 6.
The note about solve(4) 4 decimals has been removed from the description.
Just recently removed ... Thus missing for best guidance/disambiguation.
Sad for the hale storm ... Be good ... Jean.
