cmpx 0.7.1

A package for different operations on complex numbers

PythonComplex

A package for different operations on complex numbers.

More details

• This package is essentially for mathematical operations on complex numbers.
• It is very easy and intuitif to use, as any mathematicain would expect.
• There is more to come on this class, like power of complex numbers.

Installation

Use the package manager pip to install cmpx.

pip install cmpx

Usage

Importing Complex class

from cmpx import Complex

Different instanciations of Complex class

# Instanciation 1
number = Complex() # --> Real = 0, Imaginary = 0
print(number)
# Instanctiation 2
number = Complex(42) # --> Real = 42, Imaginary = 0
print(number)
# Instanciation 3
number = Complex(12, -3.2) # --> Real = 12, Imaginary = -3.2
print(number)
# Instanciation 4
number = Complex(im=13.2, re=5) # --> Real = 5, Imaginary = 13.2
print(number)
# Instanciation 5
number = Complex(re=3, im=-2.4, restore=False) # restore argument is by default True, whenever an error occurs on operation, the last result will be restored to the object, else if it is False then the object will be simply None.

Basic operations

num1 = Complex(re=3, im=-2.5)
num2 = Complex(re=4.2, im=13.2)
# Summation
print('({}) + ({}) = {}'.format(num1, num2, num1 + num2))
# Substraction
print('({}) - ({}) = {}'.format(num1, num2, num1 - num2))
# Multiplication
print('({}) * ({}) = {}'.format(num1, num2, num1 * num2))
# Division
print('({}) / ({}) = {}'.format(num1, num2, num1 / num2))
# Floor division
print('({}) // ({}) = {}'.format(num1, num2, num1 // num2))
## Affecting the result directly on the number
# Summation
print('({}) += ({})'.format(num1, 2), end=' --> ')
num1 += 2
print(num1)
# Substraction
print('({}) -= ({})'.format(num1, num2), end=' --> ')
num1 -= num2
print(num1)
# Multiplication
print('({}) *= ({})'.format(num1, 2), end=' --> ')
num1 *= 2
print(num1)
# Division
print('({}) /= ({})'.format(num1, num2), end=' --> ')
num1 /= num2
print(num1)
# Floor division
print('({}) //= ({})'.format(num1, 2), end=' --> ')
num1 /= 2
print(num1)
# Congugated of a complex number
print('con({}) = {}'.format(num2, num2.con()))
# Module of a complex number
print('mod({}) = {}'.format(num2, num2.mod()))

Comparisons of Complex numbers

num1 = Complex(im=3.1, re=-5)
num2 = Complex(im=-1.5, re=0.6)
# Greater than
if(num1 > num2): print('({}) > ({})'.format(num1, num2))
# Greater or equal
if(num1 >= num2): print('({}) >= ({})'.format(num1, num2))
# Less than
if(num1 < num2): print('({}) < ({})'.format(num1, num2))
# Less or equal
if(num1 <= num2): print('({}) <= ({})'.format(num1, num2))
# Equal
if(num1 == num2): print('({}) == ({})'.format(num1, num2))
# Not equal
if(num1 != num2): print('({}) != ({})'.format(num1, num2))
