Webarctan 实现应该是单调的；也就是说，如果 x ，那么x86处理器中FPATAN指令的 arctan（x）实现通常是专有的。要计算arctan或其他（逆）三角函数，常用算法遵循三步过程： 用于将完整输入域映射到窄间隔的参数缩减; 窄区间上的核近似计算（主近似区间） Webarctanh is a multivalued function: for each x there are infinitely many numbers z such that tanh (z) = x. The convention is to return the z whose imaginary part lies in [-pi/2, pi/2]. For real-valued input data types, arctanh always returns real output.
