How do I round a floating point number to two decimal places?
We can do this using Python’s round()
function, which rounds a given number to a specified number of decimal places. For example:
my_number = 9.489999999999 rounded = round(my_number, 2) print(rounded) # will output "9.49"
Due to the limitations of floating point arithmetic, the round()
may sometimes produce unexpected results. If this is undesirable, consider using the decimal
module as a replacement for floating point numbers.
