There are three numeric types in Python:
Variables of numeric types are created when you assign a value to them:
x = 1 # int y = 2.8 # float z = 1j # complex
To verify the type of any object in Python, use the type() function:
print(type(x)) print(type(y)) print(type(z))
Int, or integer, is a whole number, positive or negative, without decimals, of unlimited length.
x = 1 y = 35656222554887711 z = -3255522 print(type(x)) print(type(y)) print(type(z))
Float, or "floating point number" is a number, positive or negative, containing one or more decimals.
x = 1.10 y = 1.0 z = -35.59 print(type(x)) print(type(y)) print(type(z))
Float can also be scientific numbers with an "e" to indicate the power of 10.
x = 35e3 y = 12E4 z = -87.7e100 print(type(x)) print(type(y)) print(type(z))
Complex numbers are written with a "j" as the imaginary part:
x = 3+5j y = 5j z = -5j print(type(x)) print(type(y)) print(type(z))
You can convert from one type to another with the int(), float(), and complex() methods:
Convert from one type to another:
x = 1 # int y = 2.8 # float z = 1j # complex #convert from int to float: a = float(x) #convert from float to int: b = int(y) #convert from int to complex: c = complex(x) print(a) print(b) print(c) print(type(a)) print(type(b)) print(type(c))
Number data types store numeric values. They are immutable data types, which means that changing the value of a number data type results in a newly allocated object.
Different types of Number data types are :
Let’s see each one of them:
int (Integers) are the whole number, including negative numbers but not fractions. In Python, there is no limit to how long an integer value can be.
Example 1: Creating int and checking type
num =-8 # print the data type print(type(num))
Example 2: Performing arithmetic Operations on int type
a =5 b =6 # Addition c =a +b print("Addition:",c) d =9 e =6 # Subtraction f =d -e print("Subtraction:",f) g =8 h =2 # Division i =g //h print("Division:",i) j =3 k =5 # Multiplication l =j *k print("Multiplication:",l) m =25 n =5 # Modulus o =m %n print("Modulus:",o) p =6 q =2 # Exponent r =p **q print("Exponent:",r)
Addition: 11 Subtraction: 3 Division: 4 Multiplication: 15 Modulus: 0 Exponent: 36
This is a real number with floating-point representation. It is specified by a decimal point. Optionally, the character e or E followed by a positive or negative integer may be appended to specify scientific notation. . Some examples of numbers that are represented as floats are 0.5 and -7.823457.
