abstract: A round-off error, also called rounding error, is the difference between the calculated approximation of a number and its exact mathematical value. Numerical analysis specifically tries to estimate this error when using approximation equations and/or algorithms, especially when using finitely many digits to represent real numbers (which in theory have infinitely many digits).

In many cases, the round-off error can be managed, even over really complex computations, such that the top 6-8 decimal places are correct.

在许多情况下，舍入误差是可以控制的，即使在很复杂的计算，使得上部6 - 8位小数是正确的。

However, for negative values of x, roughly -4 and lower, the algorithm used to calculate Math.exp is relatively ill-behaved and subject to round-off error.

不过，对于负值的x，一般是- 4以下的数字，用于计算Math . exp的算法表现很差，并且容易出现舍入错误。
