This is a Python script and library to encode, decode and format numbers including fractions and exponential notation in radixes/bases other than decimal, such as octal, dozenal/duodecimal, hexadecimal, base57 and base62. The radix can also be determined by any number of digits specified: 0123456789ab...
- Python 3
From the Python Package Index:
pip install num-radix
Or download and run:
python3 setup.py install
Use the --help argument for help.
num-radix --help
By default, the script encodes and decodes in dozenal.
This outputs '6X,534;3000' encoded in dozenal.
num-radix --encode 142456.25 --format ',.4f'
The format string causes the output to have a scale of 4 and every 3 integer digits to be separated by a comma. The format is given in Python format string syntax.
Format with e-notation. This outputs '4;133X82e-0E'.
num-radix --encode 0.000000000005526745 --format '.6e'
Encode in hexadecimal.
num-radix --encode 142 --base hex
Decode back to a decimal from dozenal.
num-radix --decode '6X534;3'
The input and output can be piped. Each line of input is encoded (or decoded) and output on a new line.
echo -e "142\n4353" | num-radix --encode - | cat
Import the library.
from num_radix import Radix
Create a radix.
dozenal = Radix.dozenal()
hexa = Radix.hex()
base20 = Radix("0123456789ABCDEFGHIJ", sep="|")
Encode with the radix object.
dozenal.encode(3546)
dozenal.encode(142456.25, "013.4f")
numbers = [142456.25, 34, 0.000345]
"These numbers {:013.4f}, {}, {:e} are in dozenal".format(*dozenal.wrap(numbers))
Encoding date & time.
from datetime import datetime
now = datetime.now()
dozenal_now = dozenal.wrap(now.timetuple()[:6])
"{}-{:02}-{:02} {:02}:{:02}:{:02}".format(*dozenal_now)
Decode with the radix object.
dozenal.decode("6X534;3")
There are more examples in the demo section at the end of the __init__.py file.
