Python. 在Python中,内置的`round()`函数用于对数字进行四舍五入操作。 python. 基本的四舍五入。 num1 = 3.14159. rounded1 = round(num1). print(rounded1). 保留指定小数位数。 num2 = 3.14159. rounded2 = round(num2, 2). print(rounded2). 在上述代码中,第一个`round()`函数没有指定保留的小...

doesn't match the string representation of NaN there, but differs from one Python level to another. Use of Decimal as in the patch helps to fix that, so I'm expanding the scope of this ticket to cover both, and will add tests for floatformat given non-ASCII, infinities, and NaN ...
