摘要翻译：
对IEEE浮点标准中递归函数仿真的精度进行了改进。结果表明，在递归函数的模拟中，向负无穷大舍入和向正无穷大舍入的平均法比通常的标准舍入法有更好的结果。一般说来，该方法提高了一位数的精度，并避免了在logistic映射中与正确的平稳区的偏离。数值研究表明了该方法的有效性。

英文摘要：
An improvement on precision of recursive function simulation in IEEE floating point standard is presented. It is shown that the average of rounding towards negative infinite and rounding towards positive infinite yields a better result than the usual standard rounding to the nearest in the simulation of recursive functions. In general, the method improves one digit of precision and it has also been useful to avoid divergence from a correct stationary regime in the logistic map. Numerical studies are presented to illustrate the method.
