radix-ops 0.2.0

Convert between radices and perform arithmetic.

radix-ops

Convert numbers - both integer and floating-point - from one base to another. Perform arithmetic operations in a given base.

Installation

pip install radix-ops

Usage

from radix import Num

a = Num(20, 16)    # The number 20 in base 16
b = Num('ff', 16)  # FF or 255 in base 16

print(a.to(2))     # Convert to base 2 (100000)
print(a + b)       # Result in base 16 (11F)

An easier way to evaluate expressions:

from radix import expr

# All numbers in base 16. result is a `Num` instance.
result = expr('a + b * c', 16)

print(result)  # prints 8E
print(result.to(10))  # prints 142

Examples

>>> from radix import Num, expr
>>> Num(value='FE', base=16).to(base=10)
254
>>> Num(1100, 2).to(10)
12
>>> Num(10.75).to(16)  # When base is 10, it can be omitted.
A.C
>>> Num(10.75).to(2)
1010.11
>>> pi = 3.141592653589793
>>> Num(pi).to(16)
3.243F6A8885
>>> Num(-1001, 2).to(10)
-9
>>> (Num('1a', 16) - Num('ff', 16)) * Num(2, 16)  # (26 - 255) * 2 = -458 = -0x1ca
-1CA
>>> expr('-fe', 16, show=True).to(10)
-Num('fe', 16)
-254
>>> expr('b / (a + 1.5) * 2', 12)

Note

1. Base should be between 2 and 36.
