RebelBase

RebelBase is a Python package for working with numbers of any base.

Full documentation is online at rebelbase.dev.

What does RebelBase do?

Want to work with base 3 numbers? We've got you covered.

from rebelbase import Base3

n = Base3(42)           # Represent decimal 42 in base 3

print("n:    ", n)      #  "1120" (Decimal 42     == base 3  1120)
print("n + 1:", n + 1)  #  "1121" (Decimal 42 + 1 == base 3  1121)
print("n - 1:", n - 1)  #  "1112" (Decimal 42 - 1 == base 3  1112)
print("n / 2:", n / 2)  #   "210" (Decimal 42 / 2 == base 3   210)
print("n * 2:", n * 2)  # "10010" (Decimal 42 * 1 == base 3 10010)

n = Base3("212")        # Create the base 3 value 212

print(int(n))           # "23"    (Base 3 212     == decimal 23)

Need to make your own bonkers base 5 system with vowels for digits? No problem.

from rebelbase.number import Number

class Base5(Number):
    @classmethod
    def digits(cls) -> tuple[str, ...]:
        return ("A", "E", "I", "O", "U")

n = Base5(42)           # Represent decimal 42 in base 5

print("n:    ", n)      # "EOI" (Decimal 42     == base 5 EOI)
print("n + 1:", n + 1)  # "EOO" (Decimal 42 + 1 == base 5 EOO)
print("n - 1:", n - 1)  # "EOE" (Decimal 42 - 1 == base 5 EOE)
print("n / 2:", n / 2)  #  "UE" (Decimal 42 / 2 == base 5  UE)
print("n * 2:", n * 2)  # "OEU" (Decimal 42 * 2 == base 5 OEU)

n = Base5("OOO")        # Create the base 5 value OOO

print(int(n))           # "93"  (Base 5 OOO     == decimal 93)

A Number can be created with optional zero support for any base.

Numbers can be initialised with their decimal value or string representation.

A ton of Python operations -- including addition, subtraction, floor and true division, multiplication, modulo and exponentiation -- work out of the box.

Installation

RebelBase requires Python 3.9 or later.
