在上面的代码中,我们使用{:.2f}将浮点数num_float格式化为保留两位小数的字符串。然后通过print()函数输出该格式化后的字符串。 完整示例 下面是一个完整的示例,将字符串转换为两位小数数字: AI检测代码解析 defconvert_to_two_decimal_places(num_str):num_float=float(num_str)formatted_num="{:.2f}".format...
print("Area = ", round(area, 2)) Output: Area = 78.54 💡 Method 3: Using the Decimal Object Another workaround to our problem is to use the Decimal object, and the quantize function to return a float value with two decimal places. quantize method returns a value by rounding the fi...
Now, if you observe the above output of the print statement, you will see that there are three decimal places after the decimal point. A question arises here that, what if the programmer needs to print only the float value to a given number of decimal places. Like for example, in the ...
Now, let’s round this value to two decimal places. We use the round() method. The round() method. lets you round a value to the nearest integer or the nearest decimal place. We also print the amount each friend has to contribute toward dinner to the console: rounded_value = round(...
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...
>>> num = 4.123956>>> f"num rounded to 2 decimal places = {num:.2f}"'num rounded to 2 decimal places = 4.12'如果不做任何指定，那么浮点数用最大精度 >>> print(f'{num}')4.123956 格式化百分比数 >>> total = 87>>> true_pos = 34>>> perc = true_pos / total>>> perc0....
