=head1 NAME
Math::Bacovia::Log - Represents the natural logarithm of a symbolic value.
=head1 SYNOPSIS
use 5.014;
use Math::Bacovia qw(Log Symbol);
my $f = Log(Symbol('a'));
my $g = Log(Symbol('b'));
say (($f + $g)->pretty); #=> log(a * b)
=head1 METHODS
This section describes the methods provided by the B<Math::Bacovia::Log> module.
=head2 new
my $obj = Math::Bacovia::Log->new($value);
Constructs and returns a new B<Math::Bacovia::Log> object.
=head2 get
my ($value) = $obj->get;
Returns the internal value of the self-object.
=head2 add
$x + $y
$x->add($y)
Sum of C<x> and C<y>, using the identity:
log(a) + log(b) = log(a * b)
=head2 sub
$x - $y
$x->sub($y)
Subtraction of C<y> from C<x>, using the identity:
log(a) - log(b) = log(a / b)
=head2 neg
-$x
$x->neg
Additive inverse of C<x>, using the identity:
-log(a) = log(1/a)
=head2 eq
$x == $y
$x->eq($y)
Return a true value when C<x> and C<y> are symbolically equal.
=head1 SPECIAL METHODS
This section describes the special methods provided by the B<Math::Bacovia::Log> module.
=head2 alternatives
my @alt = $obj->alternatives;
my @alt = $obj->alternatives(full => 1);
This method uses common mathematical identities to create symbolically equivalent expressions from the self-expression.
=head2 pretty
my $str = $obj->pretty;
Returns a human-readable stringification of the self-expression.
=head2 stringify
my $str = $obj->stringify;
Returns a stringification of the self-expression.
=head2 numeric
my $num = $obj->numeric;
Evaluates the self-expression numerically and returns a L<Math::AnyNum> object.
