&par Example Description

This example demonstrates how to compare a hardware-accelerated custom ATAN2
function with the standard atan2 function in terms of performance and accuracy.
An Atan2CompareResult structure stores angles, reference angles, absolute error,
and cycle counts for both CDE (hardware) and reference approaches.
In RunArctan2Comparison, various angles are generated and converted into Q30
fixed-point format. Both the standard atan2 and a hardware-accelerated ATAN2
calculation (with precision level) are performed, and their floating-point
results are compared. This benchmark quantifies the speed and precision of the
hardware-accelerated solution for angle computations.
