You can use the {:.2f} format formatting to display a number with two decimal places. Update code: import math result = math.floor(1.4) formatted_result = "{:.2f}".format(result) print(formatted_result) #1.00 Share Follow answered Nov 2, 2023 at 14:47 XMehdi01 1 Add a comment...
下面是一个完整的示例,将字符串转换为两位小数数字: defconvert_to_two_decimal_places(num_str):num_float=float(num_str)formatted_num="{:.2f}".format(num_float)returnfloat(formatted_num)num_str="3.14159"result=convert_to_two_decimal_places(num_str)print(result)# 输出:3.14 1. 2. 3. 4. 5...
defround_to_two_decimal_places(number):return'{:.2f}'.format(number) 1. 2. 以上代码定义了一个名为round_to_two_decimal_places的函数,它接受一个数字作为输入,并返回保留两位有效数字并自动补0的结果。 示例 假设我们有一个数值列表[0.123, 1.234, 12.345, 123.456, 1234.567],我们希望将每个数值保留两...
python用format格式化数字 格式化输出单个数字的时候,可以使用内置的 format() 函数,比如: >>>x=1234.56789>>># Two decimal places of accuracy>>>format(x,'0.2f')'1234.57'>>># Right justified in 10 chars, one-digit accuracy>>>format(x,'>10.1f')' 1234.6'>>># Left justified>>>format(x,'<...
