logscale

This Python package provides a single function, order_of_magnitude(), which computes and returns the order of magnitude of a given number in a standardized string format.

The order of magnitude gives a compact representation of a number as a product of a coefficient and a power of 10, where the coefficient is constrained to lie within the interval [1/√10, √10). For more information, see the wikipedia article on orders of magnitude.

Installation

If you are using uv, you can install the package from PyPI with:

uv pip install logscale

Alternatively, with regular pip:

pip install logscale

Examples

from logscale import order_of_magnitude

order_of_magnitude(129)  # "1.3e2"
order_of_magnitude(0.0001)  # "1.0e-4"
order_of_magnitude(456)  # "0.46e3"
order_of_magnitude(70.2)  # "0.70e2"
order_of_magnitude(0)  # "0.0e0"
