I'm unable to compare numbers using the module. Actually i can only
use it to create numbers like 0 or inf or 1 or their negatives. But i

What are you doing that isn't working? "Because" if the documentation
examples don't work for you, why should this work?
#!/usr/bin/perl
use strict;
use warnings;
use Math::BigFloat;
my $$big = Math::BigFloat->new(200);
my $$other = Math::BigFloat->new(100);
if ($$big > $$other) {
print "It seems that $$big is bigger than $$other. ";
} else {
print "Actually $$other is at least as large as $$big. ";
}
Actually the following isnt working:
use Math::BigFloat;
$n = 0;
if ($n->is_zero()) {print 'you entered zero'}
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.
HTH,
