Reals is a lightweight Python library for arbitrary precision arithmetic. It
allows you to compute approximations to an arbitrary degree of precision, and,
contrary to most other libraries, guarantees that all digits it displays are
correct. It works by using interval arithmetic and continued fractions. The
bulk of this code is based on Bill Gosper's notes on continued fractions in
which he presents algorithms for doing arithmetic on continued fractions.
The reals library is characterized by:
* Correctness; the reals library uses interval arithmetic to ensure that all
the digits are correct.
* Calculations are done in a streaming way; the result of previous
calculations can be re-used.
* Uses no external libraries.
* Focus on usability.
NOTE: If this package has multiple flavors (see below), then use one of them instead of the name specified above. NOTE: This is a Python port. Instead of py312-reals listed in the above command, you can pick from the names under the Packages section.
*: Revise USES=python:... version range constraints
and strip all lower bounds of 3.9 or 3.10 because they are implied now.
python:3.9-X -> python:-X
python:3.9+ -> python
python:3.10-X -> python:-X
python:3.10+ -> python
(options such as ,build preserved)
python: bump all USE_PYTHON=distutils consumers after RUN_DEPENDS removal
Any missed ports, feel free to bump.
Any ports that need setuptools at runtime can have the devel/py-setuptools
manually added back to RUN_DEPENDS, but understand that this practice
is deprecated; see CHANGES for details.
