qalk 0.1.1

NumPy-style degree-based trigonometric helpers.

qalk

qalk re-exports NumPy's public API and adds degree-based trigonometric helpers.

Install

uv add qalk

Usage

from qalk import *

print(sind(30))        # 0.5
print(cosd(60))        # 0.5
print(arcsind(0.5))    # 30.0
print(arctan2d(1, 1))  # 45.0
print(s(1234))         # 1.23e+03
print(s([1, 20, 300])) # [1.00e+00 2.00e+01 3.00e+02]

The regular NumPy symbols are also available through the same import:

from qalk import array, pi, s, sin, sind

Development

uv sync --extra dev
uv run pytest
uv build

Release

PyPI does not allow reusing the same uploaded filename, so each publish needs a new version.

Use the helper script to bump the version, test, build, and publish in one flow:

./scripts/release.sh patch

You can also use minor or major instead of patch.
