print(“Rounded down to next integer:\n”, valuesRoundDown) 复制代码 首先,我们导入math模块。这样就可以使用math.ceil()和math.floor()舍入功能。然后,我们创建一个名为的列表values,其中包含多个浮点值。 为了将这些值四舍五入为整数,我们进行了三个列表推导。第一个round()针对每个列表值执行。其他两个在...
int函数虽然使用ROUND DOWN方式,但是是取整,得到的结果是integer。如果你的需求是要保留小数点后几位,就要使用decimal模块的接口: >>> from decimal import * >>> Decimal('1.2222').quantize(Decimal('.00'), rounding=ROUND_DOWN) Decimal('1.22') >>> Decimal('1.9999').quantize(Decimal('.00'), roundi...
round()函数可以接受两个参数,第一个参数是要进行截断的浮点数,第二个参数是要保留的小数位数。为了截断浮点数后面的小数,可以将小数部分与整数部分相加后取整数部分。具体实现如下: 代码语言:txt 复制 import math def truncate_float(num, decimal_places): integer_part = int(num) # 获取整数部分 decimal...

The // operator first divides the number on the left by the number on the right and then rounds down to an integer. This might not give the value you expect when one of the numbers is negative.For example, -3 // 2 returns -2. First, -3 is divided by 2 to get -1.5. Then -...
"Round down," while similar, is not the same. As the name implies, Round Down reduce a number to the nearest lower integer. For example - Original value Value after Round Down 10.2 10 5.23 5 The above table is an overview of how rounding down values works. You might be wondering,...
A: Python'sint()function does not support the conversion of a complex number to an integer. Attempting to do so will raise a TypeError. Q: What is the difference betweenfloor()andint()when converting a float to an int? A: Thefloor()function will always round down to the nearest integer...
ROUND_CEILING: Always round towards positive infinity. With the decimal module, you can round numbers to the desired precision using the .quantize() method. In the example below, the ROUND_UP method has been used to round up the decimal to the nearest integer away from zero. You can achiev...
