APyTypes is a Python library providing algorithmic scalar and array data types, both fixed- and floating-point in Python. The main purpose is to simplify finite word length design and simulation. Written in C++, the focus is on performance and flexibility.

APyTypes is available in the Python Package Index and can be installed with the pip package installer:

pip install apytypes

The package can now be used as:

$ python
>>> from apytypes import APyFixed
>>> fx_a = APyFixed.from_float(3.5, 4, 4)
>>> print(fx_a)
3.5
>>> fx_a
APyFixed(56, bits=8, int_bits=4)
>>> fx_b = APyFixed.from_float(1.25, 3, 6)
>>> fx_a + fx_b
APyFixed(304, bits=11, int_bits=5)
>>> print(fx_a + fx_b)
4.75

Test dependencies can be installed by running pip install [.test] and then executed by pytest.
