We already have a name for this parameter: s. Further, looking at the formula, we can assert that for any irrational r, the value must be greater than zero because if we multiply r by a positive integer (b) and then subtract another integer (a), we always end up with some fractional part.，更多细节参见谷歌浏览器下载
