Base to Base Number

base_to_base_number is a lightweight Python package for converting numbers from one base to another. It supports bases from 2 to 36, handles positive and negative numbers, and processes both integers and fractions.

Example

Features

• Wide Base Support: Convert numbers between any arbitrary bases from 2 up to 36.
• Signed Numbers: Fully supports positive (+) and negative (-) numbers.
• Fractions Supported: Handles fractional numbers with customizable precision.
• Pure Python: Lightweight implementation with zero external dependencies.

Installation

You can install the package using pip:

pip install base-to-base-number

Usage

Here is a quick example of how to use BaseNumber to parse and convert numbers across different bases:

from base_to_base_number import BaseNumber

# Initialize a number in base 16 (Hexadecimal)
# You can pass a string representation including signs (+/-) and fractions
num = BaseNumber("-1A.8", base=16)

# Convert to base 10
decimal_result = num.convert_to(10)
print(f"Base 10: {decimal_result}")  # Output: -26.50 (approximate fraction handling)

# Convert to base 2 (Binary)
binary_result = num.convert_to(2, precision=4)
print(f"Base 2: {binary_result}")

API Reference

BaseNumber(number_str: str, base: int = 10)

Initializes a number object.

• number_str: A string representing the number (e.g., "1010", "FF.EE", "-45.2").
• base: The base of the input number (must be between 2 and 36, default is 10).

Methods

• convert_to(base: int, precision: int = 2) -> str: Converts the stored number to a target base with a specified fractional precision.
• get_number() -> float: Returns the internal numerical representation (base 10 equivalent).
• get_integer() -> int: Returns the integer portion of the number, base 10.
• get_fraction() -> float: Returns the fractional portion of the number, base 10.
• get_integer_raw() -> str: Returns the origianl integer portion of the number via string.
• get_fraction_raw() -> str: Returns the original fractional portion of the number via string.

Requirements

• Python 3.10 or higher.
