"values are rounded to the closest multiple of 10 to the power minus ndigits; if two multiples are equally close, rounding is done toward the even choice." 如果距离两边一样远,会保留到偶数的一边。比如round(0.5)和round(-0.5)都会

Here, we take a look at how you can use the Python function round() next time you need it: Code # Rounding off integers using round() print("Round integer 33: ") print(round(33)) # Rounding off floating point, to show that at 0.5, it rounds to the closest even number print("Ro...
Theround()function is a built-in python function. It is used to return a floating-point value that has been rounded to the provided number of decimals. Synatx: round(number, digit) If the digit argument is omitted, the closest integer to the given number is returned; otherwise, the numbe...
Rounding with an ndigits argument also returns an integer. Type: builtin_function_or_method Python 整数与 Python 浮点数有不同的实现。 Python 列表和字符串对此没有定义,因此 round([1,2,3]) 将返回 AttributeError: 'list' object has no attribute '__round__'。 同样适用于 ndarray 。但是 ...
