Abstract: Systems, methods, and other embodiments associated with high-performance arctangent computation at arbitrarily high precision are described. In one embodiment, an example method brackets an angle to a working range of an arctangent approximation polynomial. A closest index of a lookup table to the bracketed angle is determined. An angle shift for the bracketed angle is generated that is configured to move the bracketed angle to a high-precision segment of the range segments. A shifted angle is generated based on the bracketed angle and the angle shift. The arctangent approximation polynomial is evaluated at the shifted angle to produce an estimated arctangent of the shifted angle. A pre-computed arctangent corresponding to the closest index in the lookup table is retrieved from the lookup table in proximate memory. An augmented-precision arctangent is then generated from the estimated arctangent and the pre-computed arctangent.
