=head1 NAME
PGObject::Type::BigFloat - Math::BigFloat wrappers for PGObject classes
=head1 VERSION
Version 2.001
=cut
our $VERSION = 2.001000;
our ($accuracy, $precision, $round_mode, $div_scale);
# Globals
$accuracy = $precision = undef;

=head1 SYNOPSIS
use PGObject::Type::BigFloat;
PGObject::Type::BigFloat->register(); # Get all numeric and float types
my $self->{foo} = PGObject::Type::BigFloat->new(0);
$self->call_dbmethod(funcname => 'bar'); # will use this as a numeric
=head1 SUBROUTINES/METHODS
=head2 register(registry => 'default', types => ['float4', 'float8', 'numeric'])
=cut

my $self = shift @_;
my %args = @_;
croak "Can't pass reference to register \n".
"Hint: use the class instead of the object" if ref $self;

registry => $registry, dbtype => $type, apptype => $self

}
=head2 to_db
This serializes this into a simple db-friendly form.
=cut
sub to_db {
my $self = shift @_;
return undef if $self->is_undef;
return $self->bstr;
}
=head2 from_db
take simple normalized db floats and turn them into numeric representations.
=cut
sub from_db {
my ($self, $value) = @_;
my $obj = "$self"->new($value);
$obj->is_undef(1) if ! defined $value;
return $obj;
}
=head2 is_undef(optionally $set);
Return undef to the db or user interface. Can be set through apps.
=cut
sub is_undef {
my ($self, $set) = @_;
$self->{_pgobject_undef} = $set if defined $set;
return $self->{_pgobject_undef};
