1、浮点数的精度问题:由于计算机内部表示浮点数的方式,有时候round()函数的结果可能不是完全符合预期,这通常发生在需要高精度的金融计算或科学计算中。例如,round(2.675, 2)在某些情况下可能返回`2.67`而不是`2.68`。 2、四舍五入规则:round()函数使用标准的四舍五入规则,即如果小数点后的第三位是5或更大,则...
>>> import math >>> math.ceil(2.2)3 math.floor(x) 返回<= x 的最大整数 (int) Rounds x down to its nearest integer and returns that integer. >>> import math >>> math.floor(3.6)3 math.fabs(x) 返回x 的绝对值 Returns the absolute value for x as a float. >>> import math ...
Today, we’re going to take a look at how to use ROUND(), common mistakes when using ROUND(), and alternatives to the ROUND() function. An introduction to the Python ROUND() function The ROUND() function takes a single number as an input and rounds it to the nearest integer. For ex...
You can use round() to round a number to the nearest integer:Python >>> round(2.3) 2 >>> round(2.7) 3 round() has some unexpected behavior when the number ends in .5:Python >>> round(2.5) 2 >>> round(3.5) 4 2.5 is rounded down to 2, and 3.5 is rounded up to 4. ...

and almost all platforms map Python floats to IEEE 754 binary64 “double precision” values. IEEE 754 binary64 values contain 53 bits of precision, so on input the computer strives to convert 0.1 to the closest fraction it can of the formJ/2**NwhereJis an integer containing exactly 53 bit...
