*             arctangent table for cordic               *
*                                                       *
* the following table is used during cordic             *
* transcendental evaluations for sine, cosine, and      *
* tangent and represents arctangent values 2**-n where  *
* n ranges from 0 to 24.  the format is binary(31,29)   *
* precision (i.e. the binary point is between bits      *
* 28 and 27 giving two leading non-fraction bits.)      *
