摘要
给出了反正切函数的快速、高精度的计算方法，其基本策略是按照二进制定点表示的特点，将计算区间转换成易求值的区间，然后利用低次逼近法进行计算．该方法计算量小，其计算精度可达到１０－８．
Gives a fast and high precision algorithm for the are tangent funcion.According to the features of binary notation, are tangents can be calculated by a method of approximation after converting the intervals to those redily evaluated. It has a higher speed and attaining an accuracy of 10-8.
