Returns the number of real roots of poly.
Returns the i-th real root of poly, or throws an
IndexOutOfBoundsException if there is no i-th real root.
The polynomial the roots belong to.
(Changed in version 2.9.0) The behavior of scanRight has changed. The previous behavior can be reproduced with scanRight.reverse.
(Changed in version 2.9.0) transpose throws an IllegalArgumentException if collections are not uniformly sized.
A trait that can be used to retreive the (possibly approximated) real roots of the polynomial
poly.
