Classes
class	Calculable
	Abstract mother class of all mathematical objects It is not possible to implement any Calculable object. More...
class	Value
	This class embedds Numbers & Strings into a basic object. More...
class	Exponented
	Exponented objects: Operations (Sums&Products), Items, Quotients. More...
class	Item
	It's the smallest displayable element (sign, value, exponent) The value can be either numeric or literal. More...
class	SquareRoot
	It's a Exponented under a square root The Exponented can be either numeric or literal. More...
class	Operation
	Abstract mother class of Product and Sum. More...
class	Product
	Has Exponented factors & an exponent. More...
class	Sum
	Has Exponented terms & an exponent. More...
class	Quotient
	Sign, Exponented numerator, Exponented denominator, exponent. More...
class	Monomial
	A Monomial is a Product of a numeric Exponented and a literal Item. More...
class	Polynomial
	A Polynomial is a Sum of Monomials, not necessarily reduced or ordered. More...
class	Fraction
	Quotient of two numeric Sums and/or Products. More...
class	Expandable
	Mother class of all expandable objects. More...
class	BinomialIdentity
	These objects are expanded using : (a+b)² = a² + 2ab + b², (a-b)² = a² -2ab + b² and (a+b)(a-b) = a² - b² This object is a Product of two Sums but won't be displayed as is in the case of (a+b)² and (a-b)². More...
Functions
def	reduce_literal_items_product
	Returns the reduced Product made from the given literals list For example, [x, x², x**6] would return [x**9].
def	put_term_in_lexicon
	A substitute for append() in a special case, for dictionaries This method checks if a "provided_key" is already in the lexicon.

def obj::calc::put_term_in_lexicon	(		provided_key,
			associated_coeff,
			lexi
	)

A substitute for append() in a special case, for dictionaries This method checks if a "provided_key" is already in the lexicon.

If yes, then the associated_coeff term is added to the matching Sum. If not, the key is created and a Sum is associated which will contain associated_coeff as only term.

Parameters:

	provided_key	The key to use
	associated_coeff	The value to save in the or add to the Sum
	lexi	The dictionary where to put the couple key/coeff

def obj::calc::reduce_literal_items_product

(

provided_list

)

Returns the reduced Product made from the given literals list For example, [x, x², x**6] would return [x**9].

Notice that the Items' sign isn't managed here

Parameters:

provided_list

The literal Items list
