1、round函数: 1-1、Python: # 1.函数:round # 2.功能:用于返回数值经四舍五入规则处理后的值 # 3.语法:round(number[, ndigits=None]) # 4.参数: # 4-1、number:必须参数,表示需要进行四舍五入规则操作的数值 # 4-2、ndigits:可选参数,表示小数点后保留的位数,可为任意整数值(正数、零或负数)...
Sometimes you need to round to the nearest 5, 10, or any other number rather than decimal places: # Round prices to nearest 5 cents for a pricing strategy prices = np.array([9.97, 24.32, 49.99, 99.73]) rounded_nickels = np.round(prices * 20) / 20 # Multiply by 20, round, divide...
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....

Mean of 'n' Nearest Past Neighbors: 使用'k'个最近的过去邻居的均值来填充缺失值,并计算填充后数据与原始数据的均方误差(MSE)。 Seasonal Mean: 使用相应季节期间的均值,它计算了对应季节期间的均值,并使用该均值来填充缺失值。然后,计算填充后数据与原始数据的均方误差(MSE),并绘制填充后的数据与原始数据的比较...
integer_number = int(rounded_number) # Or simply: int(round(float_number)) print(integer_number) Output: 8 You can refer to the below screenshot to see the output. Theround()function rounds to the nearest integer. If the decimal part is exactly 0.5, Python rounds to thenearest even num...
python库的使用 1:print(补充) 2:math 2.1:math库包括的4个数学常数 2.2math库中的函数 幂对数函数 三角曲线函数 3:字符串处理函数 补充:sorted(str) 对字符串中的元素进行排序,返回排序后的列表,而不是字符串 reversed(str) 对字符串中
