Indeed, dealing with all the special cases involves dealing with complex roots and my implementation doesn't. So there is more work to do, but I don't think it is too much... I am confident that it will do cube roots though I should check some more of these :-)
Anyway, it seems this functionality is still some way off making it into Commons Math if indeed it does... Best wishes, Andy --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
