22 Sep 2005	Jos van der Geest	1) Does error when a <= 1 2) incorrect results for some values (e.g. 1.2) 3) Make it a function so the result is returned as a string
11 Oct 2005	Duane Hanselman	I can't understand the value of this function. When computing things numerically in double precision, why isn't 1/a sufficient? And how is 1/a represented in a way that is of value in MATLAB computations. If one gets a string result, why not just use vpa in the symbolic toolbox?
