Python Numbers


Python contains three numerical types :

  • int
  • float
  • complex

When you assign a value to a numeric type variable, it is created :

Example :-

x = 1    # int
y = 2.8  # float
z = 1j   # complex

Example :-

In Python, use the type() function to determine the type of any object :

x = 1
y = 2.8
z = 1j

print(type(x))
print(type(y))
print(type(z))

Output :-

<class 'int'>
<class 'float'>
<class 'complex'>

Int

An integer or Int is a whole number that can be positive or negative, has no decimals, and can be any length.

Example :- Integers :-

x = 1
y = 35656222554887711
z = -3255522

print(type(x))
print(type(y))
print(type(z))

Output :-

<class 'int'>
<class 'int'>
<class 'int'>

Float

A float, also known as a "floating point number", is a number that contains one or more decimals and is positive or negative.

Example 1 :-Different types float values :-

x = 1.10
y = 1.0
z = -35.59

print(type(x))
print(type(y))
print(type(z))

Output :-

<class 'float'>
<class 'float'>
<class 'float'>

Scientific numbers with an "e" for the power of 10 can also be used as floats.

Example 2 :- Float values with scientific numbers

x = 35e3
y = 12E4
z = -87.7e100

print(type(x))
print(type(y))
print(type(z))

Output :-

<class 'float'>
<class 'float'>
<class 'float'>

Complex

The imaginary part of complex numbers is represented by a "j" :

Example :- Complex floating values

x = 3+5j
y = 5j
z = -5j

print(type(x))
print(type(y))
print(type(z))

Output :-

<class 'complex'>
<class 'complex'>
<class 'complex'>

Type Conversion

The int(), float(), and complex() functions allow you to convert from one type to another :

Example Convert from one type to another:

#convert from int to float:
x = float(1)

#convert from float to int:
y = int(2.8)

#convert from int to complex:
z = complex(x)

print(x)
print(y)
print(z)

print(type(x))
print(type(y))
print(type(z))

Output :-

1.0
2
(1+0j)
<class 'float'>
<class 'int'>
<class 'complex'>

Note : Complex numbers can't be converted into another type.

Random Number

The random() function for Python is not provided, but the Python module is built-in and can be used to make random numbers.

Example :- The random module is imported, displaying a random number from 1 to 9 :

import random

print(random.randrange(1, 10))

Output :-

6
