>>> fx_a = apy.fx(3.5, int_bits=4, frac_bits=4)
>>> print(fx_a)
3.5
>>> fx_a
APyFixed(56, bits=8, int_bits=4)
>>> fx_b = apy.fx(1.25, int_bits=3, frac_bits=6)
>>> fx_a + fx_b
APyFixed(304, bits=11, int_bits=5)
>>> print(fx_a + fx_b)
4.75

Tests

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