The ProblemJump To Solution

How do I round a floating point number to two decimal places?

The Solution

We can do this using Python’s round() function, which rounds a given number to a specified number of decimal places. For example:

Click to Copy
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.
