Detailed Description

A container class for the exponents.

Exponents are of the form

where and are rational numbers and is the expansion parameter. The class stores and and provides methods for the addition and subtraction of exponents.

Constructor & Destructor Documentation

exponent() [1/3]

exponent

(

)

Default constructor.

exponent() [2/3]

exponent	(	int	arg_order_0,
		int	arg_order_1
	)

Constructor.

order_0 is initialised with arg_order_0, order_1 is initialised with arg_order_1.

exponent() [3/3]

exponent	(	GiNaC::ex	arg_order_0,
		GiNaC::ex	arg_order_1
	)

Constructor.

order_0 is initialised with arg_order_0, order_1 is initialised with arg_order_1.
