Installation¶

cordic can be installed from PyPI, GitHub, or built from source.

Prerequisites¶

• Python 3.10+
• NumPy (installed automatically as a dependency)

For source builds you additionally need:

• A C compiler (gcc or clang)
• meson and meson-python build system
• numpy (for f2py compilation)

PyPI¶

For using the PyPI package in your project, add the following to your configuration file:

[project]
dependencies = [
    "cordic"
]

cordic

pip¶

pip install --upgrade cordic

uv¶

# Add to a uv project
uv add cordic

# Or install into the current environment
uv pip install cordic

pipenv¶

pipenv install cordic

poetry¶

poetry add cordic

pdm¶

pdm add cordic

hatch¶

hatch add cordic

git¶

Install the latest development version directly from the repository:

pip install --upgrade "git+https://github.com/eggzec/cordic.git#egg=cordic"

Building locally¶

Clone and build from source to modify the C code or test local changes:

git clone https://github.com/eggzec/cordic.git
cd cordic
uv pip install .

This invokes the meson build system to compile the C sources via f2py and install the resulting extension module.

sudo apt install gcc

sudo dnf install gcc

brew install gcc

Verifying the installation¶

After installation, verify that the package loads correctly:

import cordic

print(cordic.cos(1.0))  # ≈ 0.5403
print(cordic.sqrt(2.0))  # ≈ 1.4142
print("cordic is working!")

Dependencies¶

• Python >=3.10
• numpy
