order-of-magnitude 1.5

Converts floats to SI units.

Pure Python 3 implementation to convert floats, lists of floats, NumPy arrays to International System of Units (SI) strings.

Install by:

pip install order-of-magnitude

Some examples:

import numpy as np
from order_of_magnitude import order_of_magnitude

print(order_of_magnitude.oom(1.20679264e+19))
# returns '12.1 E'
print(order_of_magnitude.oom(1.20679264e+19, decimals=4))
# returns '12.0679 E'
print(order_of_magnitude.oom(np.logspace(3, 6, num=10)))
# returns ['1.0 k', '2.2 k', '4.6 k', '10.0 k', '21.5 k', '46.4 k', '100.0 k', '215.4 k', '464.2 k', '1.0 M']
print(order_of_magnitude.oom(np.logspace(3, 6, num=10), prefix=True))
# returns ['1.0  kilo', '2.2  kilo', '4.6  kilo', '10.0  kilo', '21.5  kilo', '46.4  kilo', '100.0  kilo', '215.4  kilo', '464.2  kilo', '1.0  mega']
print(order_of_magnitude.oom(0e9))
# returns 0.0
print(order_of_magnitude.oom(np.logspace(3, 6, num=10), only_oom=True))
#returns ['k', 'k', 'k', 'k', 'k', 'k', 'k', 'k', 'k', 'M']
print(order_of_magnitude.oom(np.logspace(3, 6, num=10), prefix=True, only_oom=True))
# returns [' kilo', ' kilo', ' kilo', ' kilo', ' kilo', ' kilo', ' kilo', ' kilo', ' kilo', ' mega']
