The difference to standard library Ada.Numerics.Big_Numbers.Big_Reals: - No limits, except for the pool size; - String edit packages representing a number in a usual form (with the specified accuracy) rather than as a numerator/denominator ratio; - An equivalent of Ada.Numerics.Elementary_Functions with rational approximations; - Simple continued fractions support. Changes to the previous version: - The package Unbounded_Rationals provides an implementation of arbitrary precision rational numbers arithmetic; - The child package Unbounded_Rationals.Elementary_Functions provides approximations in rational numbers of some elementary, trigonometric and hyperbolic functions; - The package Strings_Edit.Unbounded_Rational_Edit provides string editing for arbitrary precision rational numbers; - The package Strings_Edit.Unbounded_Unsigned_Edit was optimized for better performance; - Mixed Unsigned_Integer to Integer operations were added to the package Unsigned_Integers; - The package Unbounded_Rationals.Continued_Fractions provides an implementation of simple continued fractions; - The package Strings_Edit.Continued_Fraction_Edit provides string editing for simple continued fractions; - Bug fixes in List_SetItem Python bindings; - Check_Error message in Python binding was improved, trace back output added; - Added higher level operations to create Python modules after initialization of the Python interpreter; - Added higher level operations to create Python classes AKA heap types after initialization; - An example of higher level module creation was provided; - An example of higher level class creation was provided; - IsInitialized function was added to Python bindings; - OSX project settings fixed. -- Regards, Dmitry A.
