A few words will suffice to describe how you can perform floating - point calculations in a wdm driver 一些语句将足够解释你可以如何在一个wdm驱动中执行浮点计算。
Binary representation of floating - point values affects the precision and accuracy of floating - point calculations 浮点值的二进制表示形式影响浮点计算的精度和准确性。
And the compiler performs a floating - point calculation , the rounding mode you specified will not be in effect unless 更改舍入模式,并且编译器执行浮点计算,则指定的舍入模式将无效,除非打开
By default , the compiler uses the coprocessor s 80 - bit registers to hold the intermediate results of floating - point calculations 默认情况下,编译器使用协处理器的80位寄存器保存浮点计算的中间结果。
