CEILING(number, significance),ceiling英文是天花板的意思,函如其名,返回将参数number 向上舍入(沿绝对值增大的方向)为最接近的指定基数的倍数 不论参数 number 的符号如何,数值都是沿绝对值增大的方向向上舍入,这里和ROUNDUP一样 如果number 正好是 significance 的倍数,则不进行舍入。 如果number 和 significance ...

rounded_down = round(num, -1) # 向下舍入 rounded_up = round(num, 1) # 向上舍入 print("Rounded down:", rounded_down) print("Rounded up:", rounded_up) 在这个示例中,10.4 向下舍入到最近的十位数是 10,向上舍入到最近的十位数是 20。 round() 函数的应用场景 round() 函数在 Python 中...
Now that we know what Round Down is, let's look at how to round down values in programming. How to Round Down a Number in Python? There are various methods to round down a number in python. Let's take a look at them. Method 1: Using string format This method is applicable when ...
Python2 中,round()的结果就是我们所理解的四舍五入,round(1.5)=2,round(2.5)=3。 Python3 中,round()有较大改动,round(1.5)=2,而round(2.5)仍然等于2,只有round(2.6)才等于3,这是为什么呢? 解决方案 原来Python2 的round()是四舍五入,而 Python3 的round()为四舍六入五成双,即高位为单数则进1...
decimal.getcontext().rounding = decimal.ROUND_DOWN round(2.9) 返回2 总结: round函数是Python内置函数,用于将数字进行四舍五入。它的基本用法非常简单,只需要提供一个数字作为参数, 并可选地提供要保留的小数位数。round函数采用的是”四舍六入五成双”的舍入规则,返回值的类型与参数number的类型一致。在特殊...

When the decimal2.675is converted to a binary floating-point number, it's again replaced with a binary approximation, whose exact value is: 2.67499999999999982236431605997495353221893310546875 Due to this, it is rounded down to2.67. Note: The behavior ofround()forfloatscan be surprising. Noticeround(...
For example: python print(round(2.5)) # Output: 2 print(round(3.5)) # Output: 4 In these cases, 2.5 is rounded down to 2 and 3.5 is rounded up to 4, because both 2 and 4 are even numbers. This rule ensures that the rounding operation is as fair as possible on average....
Python >>> round(2.5) 2 Gasp!Check out how round() handles the number 1.5:Python >>> round(1.5) 2 So, round() rounds 1.5 up to 2, and 2.5 down to 2!Before you go raising an issue on the Python bug tracker, rest assured you that round(2.5) is supposed to return 2. There...
