round() function
Another approach to print a float with two decimal places, is to use the round() function as shown below.
# print a float with two decimal places using the round() function
myFloat = 3.14159
myRoundedFloat = round(myFloat, 2)
print(myRoundedFloat)
First the same float value as above is assigned to the myFloat variable as an example to demonstrate the round() function.
Then, round() is used to round the float value to two decimal places.
As first argument the float is passed to the round() function.
As second argument the number of decimal places is specified, in this case 2 decimal places are wanted.
