This rounding error is the characteristic feature of floating-pointcomputation.
这舍入误差的特征是浮点计算。
2
Indicates whether the object contains an imprecise computation, such as floatingpoint operations.
指示对象是否包含不精确计算，如浮点运算。
3
The reason beyond this is that those fast algorithms do reduce the complexity of computing but still one needs to use floating-point arithmetic operations in the computation process.
