Math::Bacovia::Fraction - Represents a symbolic fraction.
use Math::Bacovia qw(Fraction Symbol);
my $f = Fraction(Symbol('a'), Symbol('b'));
my $g = Fraction(Symbol('x'), Symbol('y'));
say (($f + $g)->pretty); #=> (((a * y) + (x * b))/(b * y))
This section describes the methods provided by the Math::Bacovia::Fraction module.
my $obj = Math::Bacovia::Fraction->new($numerator, $denominator);
Constructs and returns a new Math::Bacovia::Fraction object.
my ($numerator, $denominator) = $obj->get;
Returns the internal values of the self-object.
$x + $y
Sum of x and y, using the identity:
a/b + c/d = (a*d + c*b) / (b*d)
$x - $y
Subtraction of y from x, using the identity:
a/b - c/d = (a*d - c*b) / (b*d)
$x * $y
Product of x and y, using the identity:
(a/b) * (c/d) = (a*c) / (b*d)
$x / $y
Division of x by y, using the identity:
(a/b) / (c/d) = (a*d) / (b*c)
Multiplicative inverse of x, using the identity:
1/(a/b) = b/a
$x == $y
Return a true value when x and y are symbolically equal.
This section describes the special methods provided by the Math::Bacovia::Fraction module.
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.
my $str = $obj->pretty;
Returns a human-readable stringification of the self-expression.
my $str = $obj->stringify;
Returns a stringification of the self-expression.
my $num = $obj->numeric;
Evaluates the self-expression numerically and returns a Math::AnyNum object.
