In python, we can use built-in function round() to format a float number to two decimal places. In this tutorial, we will use some examples to show you how to do.
Return number rounded to ndigits precision after the decimal point. If ndigits is omitted or is
None, it returns the nearest integer to its input.
n = 2.3123 x1 = round(n) x2 = round(n, 1) x3 = round(n, 2) x4 = round(n, 3) print(x1, x2, x3, x4)
Run this code, you can find:
- ndigits = None, x1 = 2
- ndigits = 1, x1 = 2.3
- ndigits = 2, x1 = 2.32 (2 decimal places)
- ndigits = 3, x1 = 2.312 (3 decimal places)
