| // Branchless, vectorized `atan2f`. Various functions of increasing | |
| // performance are presented. The fastest version is 50~ faster than libc | |
| // on batch workloads, outputing a result every ~2 clock cycles, compared to | |
| // ~110 for libc. The functions all use the same `atan` approximation, and their | |
| // max error is around ~1/10000 of a degree. | |

| // They also do not handle inf / -inf | |
| // and the origin as an input as they should -- in our case these are a sign | |
| // that something is wrong anyway. Moreover, manual_2 does not handle NaN | |
| // correctly (it drops them silently), and all the auto_ functions do not |
