rounding is done toward the even choice(so, for example, bothround(0.5)andround(-0.5)are0, andround(1.5)is2). The return value is an integer if called with one argument, otherwise of the same type asnumber.
Python 中的round函数 在python2.7的doc中,round()的最后写着, "Values are rounded to the closest multiple of 10 to the power minus ndigits; if two multiples are equally close, rounding is done away from 0." 保留值将保留到离上一位更近的一端(四舍六入),如果距离两端一样远,则保留到离0远...

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 ...
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...
