在Python中,`float('nan')`会生成一个NaN值,但是字符串本身并不直接表示NaN。不过,我们可以通过一些方法来判断一个字符串是否可能表示NaN。## 流程概述首先,让我们通过一个表格来概述整个判断流 字符串 Python 浮点数 javascript 怎么判断是不是NaN # JavaScript中判断是否为NaN的方案在JavaS

(-Xt and -Xs modes only) Causes the compiler to evaluate float expressions as single precision rather than double precision. This option has no effect if the compiler is used in either -Xa or -Xc modes, as float expressions are already evaluated as single precision. B.2.31 -fstore (x86)...
