[英]:python round number to n decimals源码类型:Python
# Basic syntax:
format(your_number, '.4f')

# Note, at first I tried the round() syntax like this:
round(your_number, number_decimals)
# but it didn't keep a consistent number of decimals. For example, if I wanted
# to keep 4 decimals in case where I have 5 significant digits, this would
# return:
round(3.99999, 4)
--> 4.0

# Note, the ChatGPT thread I linked to compares format() vs str.format() and
#	describes some of the ways values can be formatted.
