Frank,
Math::BigInt is in the standard Perl distribution, so you probably have it on whatever
system you
are using. Type 'perldoc Math::BigInt' on the command line for an explanation of this
module.
What the new constructor does in your example is create a new Math::BigInt object. It
will test
whether or not what you passed is a number, but other than that, it really doesn't do
anything
beyond blessing your number into the appropriate class. The benefit of this is that
you can now
take advantage of the overloaded operators that Math::BigInt creates and do arbitrary
precision
integer math. See the documentation for more details (or even better, open the module
and see
what it does -- it should teach you a lot about Perl).
