Therefore the result of a floating-pointcalculation must often be rounded in order to fit back into its finite representation.
因此浮点计算的结果必须经常圆为了适应回其有限表示。

Moreover, high precise floating number and skill of floatingpointcalculation are not needed.
它速度快、硬件兼容性良好、可调，且不需要较高的精确浮点数或是浮点运算技巧。

To analyze the rounding error of calculator floating-point Numbers arithmetic operation is the foundation of numerical calculation method's error analysis.
