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...

In the example below, f indicates the value as a floating-point number while .2 specifies the decimal places to round the number. # Example number to be rounded number = 3.14159 # Using the % operator to round to 2 decimal places formatted_number = "%.2f" % number print(formatted_numbe...
>>> 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>>> perc0.390...
Decimal.quantize()方法用于将Decimal数值按照给定的小数位数进行四舍五入或截断。如果希望强制保留两位小数,可以将小数位数设置为2,并选择四舍五入方式。 以下是一个示例代码: 代码语言:txt 复制 from decimal import Decimal, ROUND_HALF_UP def enforce_two_decimal_places(number): decimal_number = Decimal(str...
num = 3.141592653589793 decimal_places = 3 result = truncate_float(num, decimal_places) print(result) # 输出:3.141 在上述示例中,我们将浮点数3.141592653589793截断为3位小数,得到的结果为3.141。 腾讯云相关产品推荐:若您在云计算领域中需要进行浮点数截断操作,您可以考虑使用腾讯云的云函数(SCF)。云函数...
