Round to 2 decimal places using the round() function The round() function is Python’s built-in function for rounding float point numbers to the specified number of decimal places. You can specify the number of decimal places to round by providing a value in the second argument. The example...
The decimal module in Python is useful for rounding float numbers to precise decimal places. It is important for achieving precise decimal rounding, especially in financial calculations. You can use the decimal module to create Decimal objects from strings, integers, and floating-point numbers. Howev...
python num = 3.14159 rounded_num = round(num) # 四舍五入到最接近的整数,结果为 3 rounded_to_two_decimal_places = round(num, 2) # 四舍五入到小数点后两位,结果为 3.14 在float对象上调用方法应使用 .__round__() 而不是 .round(): 浮点数对象确实有一个 .__round__() 方法,这个方法...
Round Float to Decimals Write a Python program to round a floating-point number to a specified number of decimal places. Sample Solution: Round to specified Decimals using %f Function: Python Code: # Define the order amount as a floating-point number.order_amt=212.374# Print the total order...
6、考虑使用decimal模块:如果你需要更精确的控制或更可靠的舍入行为,可以考虑使用Python的decimal模块,这个模块提供了Decimal类,用于高精度的十进制数运算和舍入。 7、了解Python版本之间的差异:不同版本的Python可能对round()函数的行为有所不同,特别是Python 2和Python 3在舍入到偶数的方式上有所不同,确保你了解...

You can round up a float number as follows: round (num_float, number_of_decimal_places) or round (num_float) -> In this case the number will be rounded to no decimal place 25th Apr 2021, 2:27 PM Arthur David + 8 Use round() inbuilt function Syntax : round(float, Up to numbers...
确保输入的数据类型是数值类型,例如INT、FLOAT、DOUBLE或DECIMAL。 检查指定的小数位数是否正确,特别是当指定负数时。 代码语言:txt 复制 -- 确保数据类型正确 SELECT ROUND(CAST('123.456' AS DECIMAL), 2); -- 检查小数位数 SELECT ROUND(123.456, -1); 通过以上方法,可以确保ROUND()函数的结果符合预期。 相关...
I would expect everything to be rounded to 2 decimal places, the way thefloat64(f64), andfloat(f) datatypes are in the example above. I would also expect that boolean indexing works within the range specified, according to what that dataframe shows as its values when printed. ...
