Python 3 – Number round() 方法在Python 3中,我们可以使用round()函数来近似一个数字,这个函数的一个常见的应用场景是数据分析中,对于大量数据的处理需要进行数字精度的控制。接下来,我们将探索round()函数的使用方法。round()函数的基本用法round()函数接收一个数字参数并将其近似到指定的小数位数。例如,将3.142...
Python >>> random.seed(100) >>> actual_value, rounded_value = 100, 100 >>> for _ in range(1_000_000): ... delta = random.uniform(-0.05, 0.05) ... actual_value = actual_value + delta ... rounded_value = round(rounded_value + delta, 3) ... >>> actual_value ...
Note: The behavior ofround()forfloatscan be surprising. Noticeround(2.675, 2)gives2.67instead of the expected2.68. This is not a bug: it's a result of the fact that most decimal fractions can't be represented exactly as a float. If you're in a situation where this precision is needed...

The syntax for that would look like this: round(num, 3) Q4. In Python, the round() function rounds up or down? The round() function can round the values up and down both depending on the situation. For <0.5, it rounds down, and for >0.5, it rounds up. For =0.5, the round()...
Discover three techniques to round up numbers in Python: using Python round up methods like math.ceil() from the math module, the decimal module, and NumPy.

输出时在外层做一下类型转换，比如 print(int(candyTemperature(r,e)))或者在输出时指定显示字符格式。print('数值为整数:{:.f}'.format(candyTemperature(r,e)))python
