Under the fast (hardware float) `evalhf` interpreter your `L` evaluates to Float(undefined) for values of `k` closer to 100.</p> <p>Even under regular (software float) `evalf` there are numeric issues when done at lower working precision (ie. Digits).</p> <p>There are several ways around this. The attached worksheet shows three related and relatively simple ways of getting around it by avoiding evalhf mode computation.</p> <p><a href="/view.aspx?sf=144548/455961/error1.mw">Download error1.mw</a></p> <form name="worksheet_form"></form><!--break--> <p>acer</p> <p>The problem is numeric (floating-point) evaluation error.
