平方根不存在 sqrt_value = math.sqrt(number) rounded_value = int(sqrt_value) return rounded_value # 示例 number = 16 result = sqrt_and_round(number) print(f"The square root of {number} rounded to the nearest integer is: {result}") ...
Tip: To round a number DOWN to the nearest integer, look at the math.floor() method.Syntaxmath.ceil(x)Parameter ValuesParameterDescription x Required. Specifies the number to round upTechnical DetailsReturn Value: An int value, representing the rounded number. Change Log: Python 3+ : Returns...
math.ceil(x) 返回>= x 的最小整数 (int) Rounds x up to its nearest integer and returns that integer. >>> 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...
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...

int("25") is not an integer literal because the integer value is created from a string.When you write large numbers by hand, you typically group digits into groups of three separated by a comma or a decimal point. The number 1,000,000 is a lot easier to read than 1000000....
