Numbers with Decimals

In python a float refers to a number that has decimal places.

Below, I create a variable x that is a float and then print value for x. After this, I print out the type of the variable which is a float!

                        

                            
                                # Define the variable
            x = 3.2
            
            # Print out the value
            print('The value of x is:',x)
            
            # Print out the type of variable x is
            print(type(x))

Official Definition:

float (floating point real values) − Also called floats, they represent real numbers and are written with a decimal point dividing the integer and fractional parts. Floats may also be in scientific notation, with E or e indicating the power of 10 (2.5e2 = 2.5 x 102 = 250).

If you add a float and an int together, it results in a float! An example of this is below, and you can see the result is type float

                        

                            
                                # Declare x and y - One as an integer and one as a float
            x = 3.2
            y = 3
            
            # Create the sum
            z = x+y
            
            # Print out the value and the type
            print(z)
            print(type(z))

This will give you a new variable z which is equal to 6.2

Calling the function float(number) will turn an integer into a number that can contain decimal places.
