Python Numbers

Python supports three main types of numbers: integers, floating-point numbers, and complex numbers. Each type has its own characteristics and uses. Python also provides various built-in functions and operators to perform mathematical operations.

Integer (int)

Integers are whole numbers, both positive and negative, without a decimal point.

Explanation of Code:

x is a positive integer, and y is a negative integer.

x = 10
y = -3

x = 10

y = -3

​

Floating-Point (float)

Floating-point numbers are real numbers with a decimal point. They can also be represented in scientific notation.

Explanation of Code:

a and b are floating-point numbers, while c is a floating-point number represented in scientific notation.

a = 3.14
b = -2.5
c = 1.5e2  # Equivalent to 1.5 * 10^2 or 150.0

a = 3.14

b = -2.5

c = 1.5e2  # Equivalent to 1.5 * 10^2 or 150.0

​

Complex (complex)

Complex numbers have a real part and an imaginary part, and they are written in the form a + bj.

Explanation of Code:

d is a complex number with a real part 2 and an imaginary part 3j. e is another complex number created using the complex() function.

d = 2 + 3j
e = complex(1, -1)

d = 2 + 3j

e = complex(1, -1)

Basic Mathematical Operations

1. Addition (+)

pythonresult = x + a # Adds an integer and a float

pythonresult = x + a # Adds an integer and a float

2. Subtraction (-)

pythonresult = x - y # Subtracts one integer from another

pythonresult = x - y # Subtracts one integer from another

3. Multiplication (*)

result = a * b  # Multiplies two floats

result = a * b  # Multiplies two floats

4. Division (/)

result = x / y  # Divides one integer by another

result = x / y  # Divides one integer by another

5. Floor Division (//)

result = x // y  # Performs floor division

result = x // y  # Performs floor division

6. Modulus (%)

result = x % y  # Returns the remainder of the division

result = x % y  # Returns the remainder of the division

7. Exponentiation(**)

result = x ** 2  # Raises x to the power of 2

result = x ** 2  # Raises x to the power of 2

Built-in Mathematical Functions

Python provides several built-in functions for mathematical operations.

1. abs()

absolute_value = abs(-5)  # Returns 5

absolute_value = abs(-5)  # Returns 5

2. round()

rounded_value = round(3.14159, 2)  # Returns 3.14

rounded_value = round(3.14159, 2)  # Returns 3.14

3. pow()

power = pow(2, 3)  # Returns 8

power = pow(2, 3)  # Returns 8

4. max() and min()

maximum = max(1, 2, 3, 4, 5)  # Returns 5
minimum = min(1, 2, 3, 4, 5)  # Returns 1

maximum = max(1, 2, 3, 4, 5)  # Returns 5

minimum = min(1, 2, 3, 4, 5)  # Returns 1
