#F ContinuedFractionExpansionOfRoot( <P>, <n> )
##
## The first <n> terms of the continued fraction expansion of the only
## positive real root of the polynomial <P> with integer coefficients.
## The leading coefficient of <P> must be positive and the value of <P> at 0
## must be negative. If the degree of <P> is 2 and <n> = 0, the function
## computes one period of the continued fraction expansion of the root in
## question. Anything may happen if <P> has three or more positive real
## roots.

#F ContinuedFractionApproximationOfRoot( <P>, <n> )
##
## The <n>th continued fraction approximation of the only positive real root
## of the polynomial <P> with integer coefficients. The leading coefficient
## of <P> must be positive and the value of <P> at 0 must be negative.
## Anything may happen if <P> has three or more positive real roots.
