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...
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...
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(10.7):rounds the float10.7to nearest integer,11. round(5.5):rounds the float5.5to6. Example 2: Round a number to the given number of decimal places print(round(2.665,2))print(round(2.675,2)) Run Code Output 2.67 2.67 When the decimal2.675is converted to a binary floating-point nu...
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...
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...
Q2. How do you round a float in Python 3? You round off a float number to your desired decimal place using the built-in function round() in Python. Q3. How do you round a number num to three decimal places in Python? The syntax for that would look like this: round(num, 3) Q4...
To get the round value of any float, use built-in function 'round (float, digits after decimal)' . Example: round (4.54321268, 3) >> 4.543 28th Nov 2021, 10:01 PM Prithviraj Kundu + 5 I don't get it why are we use round() function on what situations?
I've also written an article onhow to round a float to N decimal places in Python. I wrotea bookin which I share everything I know about how to become a better, more efficient programmer. About Contacts Policy Terms & Conditions
