# NAME

Math::Bacovia::Exp - Represents the natural exponentiation of a symbolic value.

# SYNOPSIS

``````    use 5.014;
use Math::Bacovia qw(Exp Symbol);

my \$f = Exp(Symbol('a'));
my \$g = Exp(Symbol('b'));

say ((\$f * \$g)->pretty);    #=> exp(a + b)``````

# METHODS

This section describes the methods provided by the Math::Bacovia::Exp module.

## new

``    my \$obj = Math::Bacovia::Exp->new(\$value);``

Constructs and returns a new Math::Bacovia::Exp object.

## get

``    my (\$value) = \$obj->get;``

Returns the internal value of the self-object.

## mul

``````    \$x * \$y
\$x->mul(\$y)``````

Product of `x` and `y`, using the identity:

``    exp(a) * exp(b) = exp(a + b)``

## div

``````    \$x / \$y
\$x->div(\$y)``````

Division of `x` by `x`, using the identity:

``    exp(a) / exp(b) = exp(a - b)``

## inv

``````    -\$x
\$x->inv``````

Multiplicative inverse of `x`, using the identity:

``    1/exp(a) = exp(-a)``

## eq

``````    \$x == \$y
\$x->eq(\$y)``````

Return a true value when `x` and `y` are symbolically equal.

# SPECIAL METHODS

This section describes the special methods provided by the Math::Bacovia::Exp module.

## 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.

## pretty

``    my \$str = \$obj->pretty;``

Returns a human-readable stringification of the self-expression.

## stringify

``    my \$str = \$obj->stringify;``

Returns a stringification of the self-expression.

## numeric

``    my \$num = \$obj->numeric;``

Evaluates the self-expression numerically and returns a Math::AnyNum object.
