这舍入误差的特征是浮点计算。
This rounding error is the characteristic feature of floating-point computation.
因此浮点计算的结果必须经常圆为了适应回其有限表示。
Therefore the result of a floating-point calculation must often be rounded in order to fit back into its finite representation.
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。
By default, the compiler USES the coprocessor's 80-bit registers to hold the intermediate results of floating-point calculations.
So what that means is the compiler is actually going to first "cast" so to speak 13 from whatever it is - to a float -- to a floating point value -- and then perform the division for us.
所以这里的意思是编译器将,做“计算“,譬如13这样一个浮点数,-到另一个浮点数-,然后为我们处理除法。
