Because internally, computers use a format (binary floating-point) that cannot accurately represent a number like 0.1, 0.2 or 0.3 at all.

因为在内部，计算机使用一种非精确的(二进制浮点数)形式表示诸如0.1,0.2,0.3之类的小数。

Another advantage is that you can use format specifiers other than % s, so that, for example, you can control how many significant digits the string form of a floating-point number should display.

另一个好处是你能使用不同于%s的格式化标识符，例如，以便于你能控制更多的重要的数字怎样显示浮点数字的字符串格式。
