Floating point Numbers are not exact, and manipulating them will result in rounding errors.
浮点数不是精确值，所以使用它们会导致舍入误差。
As a result, floating point operations may result in rounding errors, yielding a result that is close to — but not equal to — the result you might expect.
因此，浮点运算可能导致舍入误差，产生的结果接近—但不等于—您可能希望的结果。
To analyze the rounding error of calculator floating-point Numbers arithmetic operation is the foundation of numerical calculation method's error analysis.
