Thanks. I got that corrected. Actually, in my code, $n wasnt a
Math::BigFloat OBJECT.

This isn't working because 0 is an integer, not a Math::BigFloat object. You
can get Perl to represent all your /floating-point/ constants as Math::BigFloat
objects by changing the use line to
use Math::BigFloat ':constant';
which makes
$$n = 0.0;
if ($$n->is_zero) {print 'you entered zero'}
work as you expected.
