> ContinuedFraction: "maxIterations" argument
> -------------------------------------------
>
> Key: NUMBERS-46
> URL: https://issues.apache.org/jira/browse/NUMBERS-46
> Project: Commons Numbers
> Issue Type: Bug
> Reporter: Gilles
> Assignee: Gilles
> Priority: Minor
> Fix For: 1.0
>
>
> In class {{o.a.c.numbers.fraction.ContinuedFraction}}, method {{evaluate}} is
> declared as
> {code}
> public double evaluate(double x, double epsilon, int maxIterations)
> {code}
> Calling
> {code}
> cf.evaluate(x, eps, 1)
> {code}
> will raise an exception:
> {noformat}
> org.apache.commons.numbers.fraction.FractionException: maximal count (1)
> exceeded
> {noformat}
> At first sight, the check
> {code}
> if (n >= maxIterations) {
> {code}
> should rather be
> {code}
> if (n > maxIterations) {
> {code}
> However, it would also seem that the loop counter is wrong:
> {code}
> while (n < maxIterations) {
> {code}
> since setting {{maxIterations}} to 1 will in effect execute _zero_
> iteration...
