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))
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
# 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.
