Actually the following isnt working:
use Math::BigFloat;
$n = 0;
if ($n->is_zero()) {print 'you entered zero'}

Umm, that is because $n is not a Math::BigFloat. Math::BigFloat is
not a pragma, it is a class that overloads the math operators so it
can be used like a normal number.
#!/usr/bin/perl
use strict;
use warnings;
use Math::BigFloat;
my $n = Math::BigFloat->new(0);
print "you entered zero\n" if $n->is_zero;
$n += 1;
print "is it still zero?\n";
if ($n->is_zero) {
print "yes! How odd.\n";
} else {
print "no.\n";
}
