How to limit floats to X decimal points in Python?
There are a few different ways to limit the number of decimal places for a float in Python. Here are three options:
- Use the
round()function:
x = 3.14159265
rounded = round(x, 2) # 3.14
- Use string formatting:
x = 3.14159265
rounded = "%.2f" % x # 3.14
- Use the
format()function:
x = 3.14159265
rounded = "{:.2f}".format(x) # 3.14
In all three cases, the value of rounded will be the float 3.14, which is x rounded to two decimal places.
