complexint 0.0.6

A complexint class, for using large complex numbers which exceed the precision offered by the builtin complex which uses doubles.

This library provides a complexint class.

This class acts just like Python's built-in complex except it is backed by Python integers instead of doubles. This allows for infinite precision.

Example

from complexint import complexint

a = complexint(1, 2)
b = complexint(3, 6)

c = a * b
print(c)  # Outputs "-9+12j"

print(type(c.real))  # Outputs "int"

Disclaimer

This is intended for use with discrete mathematics, and ideally will be limited to the operations: add, sub, mul, and pow.

Trying to divide using this class, or using floats with this class, will result in integer conversion cutoff.

As an example of this problem, note the equivalences below:

from complexint import complexint

a = complexint(3, 6)

print(a / 3)  # Outputs "1+2j
print(a / 3.5)  # Outputs "1+2j"

print(a + 1)  # Outputs "4+6j"
print(a + 1.5)  # Outputs "4+6j"
