in thread Approximating Square Roots

There was an intermediate step where I was using bdiv() and badd() and the like. The results were the same. And with Math::BigFloat, once you've created a new() item, it isn't expressly necessary to use bdiv(), bpow(), etc. You can use standard math operators, which is what I chose to do in this most recent version simply for readability. It was easier (to me, at least) to follow the logic.

    Sorry for the late answer, found your question by chance via Google.
    You probably stumbled over one of the many bugs in the old BigFloat package. There is a newer, much improved version on CPAN, and you should give it a try. It also has a bsqrt() function, that actually works ;) 
        use Math::BigFloat v1.22;

    $x = Math::BigFloat->new('1234.567');

    print "square root of $x is ",$x->bsqrt(),"\n";
