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.
