inf(指数位均为1,尾数位全为0) denormal(指数位全为0) round to nearest even(为了防止每次舍入造成数据分布的整体变化,IEEE设计了nearest to even舍入模式,根据浮点数据判断最后一位是否进位1。这里有两种情况:1、当舍弃数大于0x1000...,或2、浮点数最后一位为1,并且舍弃部分恰好等于0x1000...) 下面开始计...
在上面的示例中,我们定义了一个名为RoundToNearestInteger的自定义函数,该函数接受一个浮点数和一个表示要保留的小数位数的整数作为参数,函数内部使用了乘法和加法操作来将浮点数乘以10的幂次方,然后使用Math.Floor方法向下取整,最后再除以10的幂次方得到最终的结果,在Main函数中,我们调用了RoundToNearestInteger函数来进...
